Software Testing vs. Debugging

Software Testing vs. Debugging



Software testing is more than just finding errors in software source code. It serves more complex function in software development than just unearthing script errors. Although software test is described as the process of executing a system with the purpose of finding defects it is more involved in ensuring software's reliability and determining if it meets the required outcome. It also greatly deals with software's verification and validation.

One primary purpose of software testing is to evaluate the capabilities or attributes of software's capability to satisfactorily meet the standards and customer requirements. But one has to remember that software test is not an absolute measure of quality. Testers' job is to test not to create therefore it is the responsibility of software developer to build a quality software for the testers to perform a quality test on a quality program. The function of a tester is to point out the bugs and weaknesses of the software it is, again, up to developers to act upon it. Testing can never completely establish the correctness of computer software it simply provide a criticism or comparison of the product to the existing standards, specifications and user requirements.

Testers is not equal to bug-finders, bug-finders are wannabe testing professionals whose idea of software testing is autopsying the codes to uncover bugs. Real and mature software testers are more concern with the issue of verification and validation of rather than just bug-digging. They focus on verifying and validating if the software passes or reaches the desired standards or requirements before considering it for general use. They are the one responsible for throwing and answering the questions: Did we develop the software right? Did we develop the right software?

He believe that their job is only to uncover bugs must then seek maturity and explore opportunities and learn how to become more productive in this field. Challenge themselves to become a greater asset to the team rather than just a bug-finder.

How to write a Test Case?

How to write a Test Case?


In software testing test case (TC) writing is one of the important activities. Many things will be left out if you are not following the proper process in this area. In this article let us try to identify some of the critical areas what you must keep in your mind while writing TCs for your project.
  1. TC must contain clear definition of the condition for which you are testing the application. In any standard test cases template, there is a precondition section present so make sure you fill that up properly. So if you are testing login function under 50% load for performance testing in the precondition mention "system is having 50% process utilization." So later on if the client wants to check for what condition, you have checked this TC, they can refer the precondition section.  

  2. TC must be clearly traceable to a requirement. The ultimate goal of any testing is to make sure that you have TCs for each requirement. It is a good practice to create a requirement traceability matrix at the end of test-case writing and validate if any requirement is missed and does not have a corresponding test case to cover.  

  3. TCs must have very clearly stated steps. So in the test step section make sure you put the steps in such a way that anybody even new in the project can run it. After writing the test-case do a dry run in your mind and see if any step is missing. It also helps during bug fixing for the development team. You can just send it to them in excel or attach it in your defect. If the steps are clear and simple enough they will be able to reproduce the bug without asking you for more clarification.  

  4. For each test, TC makes sure you clearly mention the expected results or what would happen after execute the steps. If in the step you have four validation condition, then for each validation, you must have an expected result. For example, if in the first step I say user logs in with proper user id and password, then the expected result would say the user login successfully to the dashboard and can see various buttons in the dashboard screen. Similarly, if the user does not have enough permission to see all the buttons, you may mention user logs into the system successfully but only can view the screen but edit button will be disabled until the user, etc. Make sure you write it for all such actions. During testing the tester should not try to assume what is the expected outcome and miss a defect.  

  5. Last critical think of TC writing is test data preparation. After writing the test case you must attach the proper data against it. Again this has to be done for each step. In our example test where a user logs into the system with a role with all permission and limited permission, you need to find at least two user accounts. You can attach the test data in the test case itself by adding one column called test data.

These are some of the steps very critical during test case writing. Furthermore, make sure all these areas are reviewed in several layers to ensure proper quality.

What Is Usability Testing?

What Is Usability Testing?


In this article, we will try to answer one of the frequently asked questions in software testing, and that is "What is usability testing?" This is one kind of validation where we test the system from user's perspective.

The purpose of this is to check the following areas:

Does the UI of the system meets all the user requirement or after using one time the user will never use the application again? Here typically first thing we check is the application navigation system to make sure all the pages or forms can be navigated from one to another without any error.  Next we check if the look and feel, screen labels are correct and unambiguous. Third all the standard windows controls are present. This is very important for the usability perspective as most of the users are used to with all the standard windows or browser controls and if some of them are missing or in the wrong place they may face difficulty to navigate through the application. 

The next major objective of the usability testing is to test the application in a lab environment which closely simulated the actual user environment. We also try to match the load of the production systems. Typically, production like data will be used during this testing to get a realistic result from the application under test. This mitigates the risk of having surprised after prod deployment of the application.

At the end of the usability testing you have baseline user performance measure in place, which can be shown to the business users to set the correct expectation.
So now when we know what are the goals for usability testing let us check next. What are the steps to perform it?

1. Decide a handful of test case scenarios which you should run as a part of usability testing. The selection criterion is very simple. Talk to the end users and try to understand the frequently used functions in the business today. Often you may even use a back end system such as DB query or service calls, etc. to get these statistics.

2. Next select some end users who can take participation in this testing. Actual business users who run the application day to day would be really good in this part.

3. Set up the actual test lab for usability testing. As I have already mentioned it has to be as close as possible to the actual production environment with the similar kind of data loaded.

4. Provide the end used set of test cases to run and observe and write down all the problems they face during test execution. Collection of quantitative and measurable data is very important here. That is why it is a good idea to have some number of test coordinator who would actually write those observations on the behalf of the end users. Because they are not testing professionals so you cannot expect them to write defects for you.

5. Based on the observations send the recommendations to the development team.

What is Agile Software Testing?

What is Agile Software Testing?

History

To understand the testing process in Agile development methodology, it is important to understand the paradigm of Agile development. The Agile Development paradigm is not new. Although Agile Software Development Manifesto was launched in February 2001, the concepts existed well before this and have been expressed in different ways. Development methodology spiral is an example.
 
What is Agile Software Development?

 The Agile Software Development focuses mainly on an iterative development and delivery. Developers and end users to communicate closely, and the software is built. A working software is delivered in a short period of time and based on the comments more features and capabilities are added. The emphasis is on customer satisfaction by providing software quickly with minimal features and improvisation based on the feedback. The client is closely involved in software design and development process. Delivery times are short and the new code is built on the previous one. Despite this, the quality of the product can not be called.

What is the test in a scenario of Agile development?

 The test strategy and the Agile development approach could be very different from the traditional bureaucracy. In fact, it can vary with the needs of the project and the project team. In many scenarios it make sense to not have a team of test. The above statement should be understood carefully. Failure to have a testing team, we do not consider the tests to be less important. In fact, testing can be more effective in short, by people who know the system and its objectives very well.

For example, some teams of Business Analysts could make a few rounds of tests each time the software version is available. Business Analysts understand the requirements of the company and the test software to check if it meets the requirements.

Developers test the software in May. They tend to understand the system and can verify the test results in a better way. Testing for Agile Software Development requires innovative thinking and the right mix of people should be selected for the test.

What is Manual Testing?

What is Manual Testing?

Manual QA Testing is carried out to identify defects in the test software pertaining to usability testing along with GUI testing area. It proves to be a highly effective form of IT testing since it detects a certain class of bugs successfully, which cannot be detected using test automation technique

Now the question arises when to use manual QA testing? Well, the answer to this question redirects us to certain instances listed below.

Let us take the case of installations and setups where loading of CD-ROMs and tapes is done by the tester. Also, it's needed in the instance of localization wherein the tester screens & decides if the translation is making some sense or not, whether it's appropriate or not etc.

Manual QA testing is also required in the case of error handling and recovery in which the tester needs to be involved in test execution thus highlighting again on the significance of manual testing. Besides the cases listed above, manual QA testing is also called for while reconfiguring systems, installing some new software, which require manual intervention. It's also much required to screen intricacies/errors associated with UI & workflows. Along with that, it's also used in documentation. However, it must not be conducted during the last phases of Software Development Life Cycle (SDLC).

It's time for us to jump on to the next sub-topic—how to use manual testing? Let us take a glance at the how manual testing method is used. The process is screened and assessed across all phases of SDLC. However, the execution can go on simultaneously with the normal manual testing process. While test cases are prepared and executed, the supervisory authorities can continue using the results of that process. The testing of interface is then done between the users and application system. However, there are a large number of factors that impact the efficacy of manual QA testing such as test case completion degree and in-depth documentation done.

Automation Tools for Regression Testing

Automation Tools for Regression Testing


Once the application code changes it is carried out its re-testing which is also called regression testing. This is done to make sure that everything is working correctly and that the changes did not result in any new software bugs.

The destination of this type of testing is to verify that operating functions are not broken after the change of the code.
It is important to conduct regression testing as often as possible (for example, after new software build), so that code modifications that damaged how application works can be quickly identified and fixed.

As soon as there is something to test, then regression testing begins. Regression testing begins as soon as there is something to check at all. The regression test suite grows as the application moves ahead and test engineers add test cases that test new or rewritten code.  Soon the suite may extend to thousands of test cases that cover various application functions. Obviously there is a fact that a person cannot repeat all the tests and analyse their results. That is why at this moment automation regression tests are necessary.

When should we start regression testing?

At that moment, when a programmer fixes a software bug or adds a new code for new functionality of the system - at this point regression testing begins. It is a quality measure to check that new code complies with old code and unmodified code is not getting affected. Most of the time testing is used to check the recent changes in the system. In such situation testing only affected application area in necessary to complete the testing process in time with covering all major system aspects.

What do we include in regression testing?
  • Rerunning the previously conducted tests
  • Comparing current results with previously executed test results.

How much time is needed for regression testing?

This depends on the scope of new added feature. If the scope of the fix or feature is large then the application area getting affected is quite large and testing should be thoroughly including all the application test cases. But only if the tester receives input from the developer on the scope, number and nature of changes, only then it can be effectively.

Regression testing and changes in GUI

It is distressing to make graphical user interface regression testing when GUI structure is altered. The test cases written on old GUI either get archaic. Update of the regression testing test cases means GUI test cases are changed according to new GUI. But if you have many GUI test cases, then this job becomes unwieldy difficult.

Tools for automated regression testing

Automated regression testing is the testing area where we can automate most of the testing efforts. Expected results so automating these test cases are time-saving and efficient method for regression testing as well as manual testing takes too much time. The degree of automation depends on the number of tests that will remain applicable over time. If test cases are varying time to time as application scope goes on increasing then automation of regression procedure will be the waste of time.

The vast majority of regression testing tools are recording and playback type. As you can imagine, this means that you will write tests on AUT navigation and test results are expected or not.
Here are some examples of tools of regression testing:
  • Selenium
  • ActiWate
  • AdventNet QEngine
  • Regression Tester
  • Rational Functional Tester
  • SilkTest
  • WinRunner
  • QTP
  • VTest
  • Watir
Most of the tools used by both functional and as tools for regression testing.

User Acceptance Testing (UAT) For Websites

User Acceptance Testing For Websites


The importance of user acceptance testing varies considerably. In some circumstances, it's founded a set of tests a program or Website must complete before delivery is acknowledged by the end personal.

A more complete way to UAT contains the end customers at every level of the development process, and for the demands of determining business and e-commerce websites, this is the importance that should be used

UAT is different from Quality assurance because it information issues that QA doesn't, like how easy and user-friendly a Website is to use rather than just the issue of whether the Website's significant features perform or not. It's possible to have a Website that goes all QA tests for basic functionality but is so challenging to use that it usually chases customers away. There are many Websites like this on the Online, and the earnings they cost organizations would probably secured the cost of adequate UAT several times over.

The objective so many professional Websites are unsuccessful on the issue of Quality is mainly due to information of the issue that professional Websites are usually designed by one people to be used by another people. In contrast to workers who have to use whatever technology their professionals choose to offer them with, customers usually have a option, and if one professional Website is too challenging to use, they'll go for an much easier to use oppositions Website nearly every time. The key to success is to create sure your organization Website is one of the easy to use ones. Unfortunately, this is easier said than done, but if you follow one of the traditional UAT techniques the objective is well within go to.

To start the UAT process, evaluate out some of the UAT Websites on the Web and acquire one of the UAT information templates that seem to fit your design's needs. Established with care. Most of the documentation available on UAT is focused at organizations developing up Websites for in house use. Therefore the UAT framework symbolizes that the end customers will have a brilliant concept of what they want, and that they will have the efficiency to communicate those needs clearly, and interacting with business circumstances. Companies developing Websites for use by customers, or other organizations, encounter an entirely different situation because it's challenging to involve customers in anything but one more items or assistance, or at best a try out of one more Website.

To get over this issue, one or more workers should be particular to indicate the end personal customers at every level of the development process. This will add to the development cost, but it will be well value it. The unique end customers particular to the project don't usually need to be greater paid workers, just those who are advisor of the end personal. Even earnings personal or employees will do for Websites promotion typical client items. For B2B Websites, relaxing program workers might be more appropriate.
