Unit testing is “a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.” (Automated Defect Prevention, 2007)
Unit testing is the testing of the components of a software individually to ensure its wholeness and quality. This white-box type of testing is generally done on the smallest separated module in isolation but this may vary by team to team with regards to their specifications of test plans. In Layman’s terms, unit testing is testing a house brick by brick and not as a whole. It is done at the coding level and makes sure that the module …show more content…
Thus, this type of testing gives independence to both the developer and tester.
• Tester do not need to have technical knowledge about programming or the internal structure.
• Test cases/plans can be made once the functional requirements are available.
Disadvantages of Black Box Testing
• It is difficult to write test cases if the functional specifications are not clear.
• Writing test cases may be slow and difficult since it is difficult identifying all the inputs in a limited time frame.
• There can be many instances of tests being repeated (pesticide paradox) that were already executed by the developer.
Implementation:
• Equivalence Partition
This approach is used in implementing Black box testing to cover various types of potential defects and errors. This avoids use of test cases that may test the same thing repeatedly and thus reduces the costs.
• Requirement Compliance
Executing Black box testing to check if the software complies with the user specifications or not is an approach used by test teams.
• Boundary Value Analysis
“Boundary value is defined as a data value that corresponds to a minimum or maximum input, internal, or output value specified for a system or component.” (IEEE Standard Glossary of Software Engineering …show more content…
• Alpha Testing
In Alpha testing, the software is used by the internal staff and they test it from the customer’s point of view. They provide the evaluation to the test team so that any necessary modifications can be made.
• Beta Testing
The software is used by a group of outsiders in a real environment. Their feedback is assessed and is used to improve the product.
Advantages of User Acceptance Testing
• The results of this test are conclusive and the final outcome of the whole software development process.
• Evaluation can be beneficial for the team for future improvement.
• Boosts customer satisfaction.
Disadvantages of User Acceptance Testing
• The test cases developed by the testers may not cover real world scenarios which the end users face. Hence, the test may prove to be a failure.
• If the tester planners are not skilled enough and have less experience with respect to how the customer’s business process works, the test case would prove to be inadequate.
