Software testing is a crucial part in developing projects. Through this process information related to the quality of the software developed is evaluated by the programmer or developer. With rising competition it seems fair to launch the product before your competitors and fix the bugs later. It does sound appealing but this would not ensure success for your product. Rather comprehending the features of your product is more important in the daily activities and eventually, in the success of any business.

Before we discuss the importance of Manual Testing, at first let us know what actually it is. It is actually a process that is followed to detect and pick up errors as well as flaws within a particular software application. Since the detection is done manually, the individual who tests the application plays the most important role as an end user when it comes to verifying as well as evaluating the features or the behavior of the application in question under various circumstances. Though it is the preliminary stage of assessment, it is needed to be executed in a seamless way before switching over to automated testing.
The principal objective of non-automatic evaluation is guaranteeing that the application that is subjected to test is free of glitches as well as defects and is working perfectly as per the specification of the requirements. Now let us see how important this type of software evaluation these days really is.
At present, even as the concept of automatic testing is fast gaining momentum in terms of popularity, this has not rendered the concept of manual evaluation totally useless. In fact, prior to starting the automatic assessment of a software application, there is an ardent need of setting up a base that will decide when and how to start the automatic evaluation. It is manual testing that forms that base and here lies its importance. This form of software evaluation helps to understand the reason behind testing, the role of quality as well as its reliability and the risks that are involved in the evaluation. Besides, it also helps in a better understanding of the risks that are associated. It also helps improving the testability through evaluation of the risk factors.
Although, there are a lot advantages that are associated with automated evaluation of software applications, the manual version has still not lost its importance and relevance whatsoever. In fact, there are certain instances where the manual variety is more important than the automatic variety. There are a number of software packages in the market, which are released successfully after solely depending upon manual testing without any type of automatic assessment whatsoever.
However, experts are of the opinion that the best way to evaluate a software application is by setting up a perfect combination of manual and automated testing and this makes manual evaluation so important in today’s context. Though you will find a lot of discussions regarding the efficacy or importance of automated discussion, there are certain cases where the manual version is more effective as well as more important than the automatic one. A perfect combination of the two varieties would provide you an error free software application with no regression bugs and this will allow you to give more thrust towards further development and enhancement of the application in question. In fact, there are certain bugs that can be detected only with the successful manual software testing.
The basic issue of non-automated testing is to know how to use each and every technique for solving various problems. Frankly speaking, when it comes to assessing whether a particular application can be used by human, the best answer is non-automated evaluation. This is because in most of the cases, automatic assessment is not able to decide whether the text or the information provided can be apprehended by the end user and here is where the importance of manual assessment comes into play. Even if there is an automatic process to do so that will be expensive. Hence, the popular notion is that, though it can well be automated, it is more feasible to manually test those effects, as this will very much provide more confidence to the users as well as much cheaper in terms of time that is taken.

Software testing has of late become an absolutely indispensable criterion so far as progress of companies is concerned. This is one activity that no company can ignore as that will have a disastrous impact on their progress and goodwill in the market, especially taking into account the cutthroat competition that is prevailing.
Now let us look into, why it becomes difficult for the companies to survive without software testing. In the present day business scenario, when each and every customer would like to pay only for picture perfect products, SW evaluation is an absolute necessity. Today’s customers need the products to be implemented as well as installed faster in order to have an edge over their competitors and this is where the real challenge lies. Successful implementation of key as well as value added features within a short period of time and on time delivery of SW to the clients are the keys to the progress of a company. This is only possible if the software is properly tested by trained professionals for a considerable period of time before the delivery. After all, who would like to accept defective software and work with the same? Hence, a thorough SW evaluation is the first and foremost condition of a product’s success, which in turn helps the business to thrive from the clients’ point of view as well as that of the developer’s.
Again, one should keep in mind that software development is a continuous process. A good company would always continuously come up with newer versions of software it has developed. Hence, it needs to maintain a tight schedule to meet deadlines. Therefore, there is a continuous shortage of time which needs to be countered while releasing newer software versions. At times, these tight schedules are reasons enough for bugs to pile up on software products. It is here where the need for evaluation or debugging arises.
Usually, evaluation is considered as one of the phases in the lifecycle of SW systems. However, one school of thought suggests that there is need of these tests in every phase of a product. Therefore, how can a company do without these evaluation processes?
In fact, in SDLC or Software Development Life Cycle, evaluation plays an extremely crucial role that helps in the improvement of performance, quality, as well as the reliability of the software in question.
The main objective behind SW evaluation is to reduce the risks that are associated with SW development. When we speak about risks, they are both technical as well as programmatic, i.e. the risk of the software not performing as intended or getting too complicated or difficult to operate or modify, maintain or browse. All these are taken care of during examining the functionality of the SW. Naturally, software testing would definitely help a company to live up to the goodwill and reputation that it has built over the years.
Most importantly, once a certain benchmark is set, that needs to be met and even crossed during subsequent period of time by a company and it is the practice of SW evaluation that helps the company in question in that.
Now surely a business can avoid the practice of SW evaluation. However, it will be an extremely risky affair for it, especially in its efforts to meet customer satisfaction. It can well fail to meet the customer requirement in terms of customization as well as quality and if that happens, that will be a huge blow to its goodwill. That is why, each and every business would like to be dead sure as well as confident about the quality of the product they are offering to their clients. Hence, there should be no prize for guessing, that no business would thrive without the contribution of SW testing.

Software related services, irrespective of the fact whether they are JMS, RESTful or SOAP, are extremely sensitive ones that involve highly critical assets of enterprise technology. It collectively forms the very base or foundation of any critical application or system. This clearly implies that problems relating to performance or functionality of these services are likely to severely disrupt the operations, putting the very purpose of the operations into doubt and disarray.
Naturally, this would make testing, especially mission-critical service testing all the more important. However, in spite of all these critical issues, a lot of companies and enterprises refrain from investing enough time, effort and manpower behind service testing. Even if and when they do so, they do not accurately follow any type of tried and tested methodology that would help guarantee repeated success. This, to say the least, proves extremely costly at the end of the day.
Therefore, when opting for mission-critical service testing it is imperative that certain fundamental parameters are taken into account to ensure that the services are ready for production.
1) Testing the Services in an exhaustive way
This is one of the most important aspects of service testing. It is imperative to be sure that you validate the software in an exhaustive way as there is need to make sure that it runs exactly the way it is expected to, on each and every possible variation of the real time operation. However, as software systems have become extremely complicated these days ideally this is not possible. Still, there is also a need to validate each and every feasible system permutation and input combination along with the software features to ensure real time efficacy.
2) Test Using a considerable volume of Realistic Data
Software applications are getting more and more sophisticated. This is expanding the role played by database testers. This is why, the need of the hour is to use a huge amount of data which are realistic as well as of high quality that can reliably represent the existing or new stress-test platforms or domains. Here it should be stated that good quality prototypes also require test data that would represent good as well as not-so-good production data.
3) Making Sure that the Services offered Are Safe
This is another fundamental clause that is essential while testing mission critical service. Now the service can be secured in two ways:
- By making sure that the service is accessible at the points of access called interfaces that they are supposed to be at.
- Configuring them in a proper way to ensure that they can be used only by the authorized users and that also in a proper and legitimate way.
Restriction can be imposed by restricting the access at kernel or the fireball. By configuring the services it can be guaranteed that they obey the commands only on a particular interface (provided that this feature is available) or by using any method you may consider appropriate.
4) Getting maximum Productivity from the Developers and Testers
This is another way of testing mission-critical services. As developers and testers would provide the best reports being the experts on the subject, you need to extract as much productivity as possible from them. This can be done by increasing the physical size of the screen or increasing the total pixel count, controlling the waiting time, lessening memory loss, increasing the continuity, lessening the time spent for rebuilding structures and so on.
5) Exhaustive Tracking of the Test Results
There is need to maintain an exclusive way of tracking the status of the testing to ascertain the end results of the test. This is to ensure that critical information available includes applications that have passed the test, those which have not or the ones that are still left untested.
6)Testing the Services against Anticipated Loads
It is imperative to ensure that the mission-critical service that is being designed is able to take on the rigour of the real world use or that can be done by conducting load testing services. In this way it will be able to ascertain what will be the performance of the application once it is live or functional in the real world.
7) Making Sure that You Govern the Services
Last but not the least, it is important to ensure that you have control over all the activities along with actions pertaining to the services that are being carried out. This will give a fair amount of idea about the status of the evaluation as well as the methods that are being followed in the evaluation. That means, once the application is live it gives an idea about how it will fare in real life or what will be the end results delivered by the application.
Following these most popular clauses would highly ensure that the application developed is flawless, effective and the client gets his money’s worth at the end of the day.

Testers have always been involved in testing and bringing to their clients varied applications that have been tested over time. This means they have immense expertise as well as knowledge on the applications which they have worked on in the past. In this day, one now has to move into the areas of user experience for testing. UAT or user acceptance testing was mostly done by short test cycles in tandem with BSAs, from where the test cases were brought ahead. However, it is the difference that comes on board which makes all the difference, so let’s take a look at how real acceptance testing can be justified.
How it goes
In traditional testing mechanisms, when the development was over and done with, traditional testing took place. This was logically correct, since testing something when it existed made more sense, and specifications could be sought as well as obtained. The codes then can be tested well and the verifiers would come out with real time results too.
Acceptance testing has changed that all, but is somewhat alike to what test driven development in sync with acceptance test driven development was. Both have tests written before the code can be brought in. However, here instead of the static document being written or a specification for the same being shown, one can have a specification which is executable and on which codes that run can be written too. The codes can be refined as well as re-factored.
With acceptance test driven development, testers now have change of work. They do not need to be around when a cycle ends, but are there right from the beginning, contributing at every step and stage. They help well with small teams, when one cannot afford to bring on board a business analyst that would be dedicated. This would be best as an idea which would help smart testers work and help, and they can keep in touch with the end users too. With them around, real time feedback comes across, which means more productivity at work.
Is it testing or not?
TEST is spoken off but it hardly is a test, say experts. Call it a tool available for goal facilitation if you please, it is a communicative method bringing everyone under one umbrella. Whatever is desired would be defined in ways non-ambiguous. When tools such as these are used, sharing with members in the team is easy, and across various languages too. Hence, no barriers or hurdles to deal with.
It allows you to focus on the problems as well as to come up with solutions. This would allow you to reap many benefits ahead, and to write important features which focus more on solutions. Yes, it takes a little time to learn a skill but the upside is that one doesn’t have to be a genius to go forward on the learning curve.
Moreover, with the tool, one doesn’t have to deal with too many documents, literally. The feature has source codes that live close to the other codes around, and none of them are dead or outdated.
The whole team can now collaborate as well as work for higher output using real time testing, right from the beginning to the end. Silos are prevented in doing so, irrespective of the team size. It is a natural way to bring the whole team together.
Team size can be small, because of the executable specifics along with the way the software works which helps pass specifics at the end of the day. Only a small number of men and women are needed to make things work using this tool, not a large group. One can sit to describe the wants while another person can work on execution.
To learn more about real acceptance testing along with how it can benefit your company, take a look online. Read reviews, client testimonials and understand the nature through which it brings revenue to businesses across the globe. Thanks to modern day technology, business owners now have more options to unburden, and this is just the tip of the ice berg which brings in more.

An organization has option to evaluate the quality of an enterprise application through both manual and automated software testing options. But the test strategy must consider evaluating both functional as well as non-functional aspects of the application. Along with the look, feel, features and functionalities of the software, it is also important to test beyond its normal operational capacity. Software stress testing is used to determine the stability and operational capacity of an application.
The key objective of the non-functional testing is to ensure that the enterprise apps do not crash in the live environment due to insufficient memory, disk space or other computational resources. Along with considering the correct behavior of the enterprise application under normal circumstances, the testing further aim to protect it in production environment by emphasizing on availability, robustness and error handing under a heavy load.
How to Protect Enterprise Apps in Live Environment through Stress Testing
Finds Critical Memory Problems
Often enterprise apps crash due to lack of adequate memory. But the flaws will not reflect in a single instance. So stress tests need to be carried out constantly to find the critical memory problems and concurrency bugs. A simple and straightforward stress test is further effective in identifying all flaws that makes the application crash. The QA engineers can simply keep on putting additional load on the server to decide the stress level required to make the software crash.
The application needs to be tested repeatedly and beyond its normal operational capacity. Unlike load testing, stress testing aims to determine the load under which the application crashes, along with what causes the failure. So the testing must be carried out continuously to ensure that the app does not crash in live environment. As the test cases need to be executed repeatedly can be automated to get better results, stress testing can also be automated. An organization also has option to choose from several stress testing tools to save both time and effort.
Along with stress testing automation, an organization also needs to concentrate on continuous integration. As most enterprises do not automate the deployment process completely, the chances of human error increase substantially. Thus, continuous integration becomes essential to minimize these potential manual errors. However, an enterprise has to invest in custom hardware to facilitate continuous integration. But the tools and hardware procured for stress testing automation can be used to integrate additional tests at the enterprise level.
In addition to the hardware, continuous integration will further require the involvement of developers and operations. The automated tests must be developed and coded properly. Similarly, the hardware must be maintained on a regular basis. So each organization has to make and implement a continuous integration strategy by involving the app developers, QA engineers and operations. The seamless coordination between these distinct teams will make it easier to decide the load under which the application crashes.
Keep Adding Heavy Load
The stress testing can be further effectuated by putting heavy loads to make the enterprise app struggle. It is always important to keep in mind that the stress testing software applications are being executed with the sole aim of making the app struggle as the load increase. Along with increasing the level of load applied on the app constantly, the stress testing needs to be done again and again without allowing the app to recover even once. The performance of an application under heavy load can be determined accurately only by trying to break it.
However, stress testing must be integrated seamlessly with load, fail-over, reliability, baseline and targeted infrastructures to generate more accurate and reliable test results. The test results can also be used to take several important decisions related to the launch and promotion of the specific enterprise application.
