Static Testing and Dynamic Testing

Static Testing and Dynamic TestingThe difference between Static Testing and Dynamic Testing is as below. Static TestingStatic Testing is a software testing method that software is not really executed. It normally checks defects for the deviations from standards, missing requirements, design defects, test plan, non-maintainable code and inconsistent interface specifications. Dynamic TestingDynamic Testing is a software testing method that software is really executed. Software is executed using a set of input values and its output...

Process When Testing A Software

Process When Testing A SoftwareHere are basic activities of testing process that I normally use when I need to execute testing a software. The process will start from planning and end with evaluation the process. 1. Test Planning and ControlFirst of all, we set the goal and scope of testing when we plan to do testing a software. This goal is based on the objective of the project. We define approach and plan for software testing. Then, we define the test approach which includes coverage, test resources, schedule of all the tasks, exit criteria...

Black Box Testing

Black Box TestingBlack Box Testing is a software testing method which testers use when they have no idea about software's internal algorithm. Testers only know the input and its expected output from the software which is based on specification. Test Design TechniquesTest Design Techniques are used for test case design. They include: - Equivalence Partitioning - Boundary Value Analysis - Pairwise Testing (All-pairs testing) - Decision Table - Error Guessing Advantages of Black Box Testing- Test...

Is it necessary to have Integration Testing Phase?

Is it necessary to have Integration Testing Phase?Since the Integration testing can be done in several levels, I will choose one level as example for this article. The Integration testing that I choose is the software testing for interaction between 2 systems which occurs after System Testing Phase. However, the idea from this article can be applied to other level of Integration Testing Phase as well. "Is Integration Testing Phase necessary?" This question may be in some testers' mind after they...

Software Testing in Requirement Analysis

Software Testing in Requirement AnalysisI have found that many bugs are introduced during Requirement Phase but testers can detect them during do software testing. If they can detect bugs in Requirement Phase, the cost for fixing them will be cheaper. So, it is worth to remove them during this phase. Here is some activity that tester can involve. Keep in mind that the requirement must be clearThe good requirement must be clear, measurable, testable and defined enough for system design. Moreover, the requirement must be fulfilled by using...

No resource for testing everything !!!

No resource for testing everything !!!Most issue that QA or tester faces is that the limitation of resource (time and manpower) for software testing. With this constraint, we need to decide what is the proper software testing scope and find the way to execute testing a software faster. Prioritize software testing scopeThe first thing that we need to do is to prioritize the software testing scope. We can use the software feature's  importance and likelihood / impact of failure to prioritize....

The earlier a bug is found, the cheaper it costs

The earlier a bug is found, the cheaper it costsThis is the key message showing why we need to do software testing activity as early as we can. Let's find the reason by starting with following SDLC model (V Model). It shows us that there are many phases during implementation. It starts from Requirement Phase and ends with Acceptance Testing Phase. If a problem from Requirements phase is found during System Testing phase, then it would cost more to fix than if it had been found during the Requirements...

What is Software Testing? Why do we need it?

What is Software Testing?Software Testing is the process of checking if the software can meet the user's expectation. This process can be used for testing a software for both web testing and windows application testing. Why Software Testing?Without Software Testing Process,1) The software has poor quality.2) The software may contain the critical error or bug.3) The cost of error or bug may be too high.  Why do I say that "The cost of error or bug may be too high."?  Let's see the sample of high cost bug: A hospital uses the...
