Jun 13, 2024 · Black Box Testing is suited for functional testing at higher levels, conducted by testers, while White Box Testing is more suitable for unit and integration testing, performed by developers. Both have their advantages and disadvantages, and the choice depends on project requirements and desired test coverage.

Input:Requirements, Functional specifications, design documents, source code.Processing:Performing risk analysis to guide through the entire process.Proper test planning:Designing test cases to cover the entire code. Execute rinse-repeat until error-free software is reached. Also, the results are communicated.Output:Preparing final report of the entire testing process.1. Statement Coverage
In this technique, the aim is to traverse all statements at least once. Hence, each line of code is tested. In the case of a flowchart, every node must be traversed at least once. Since all lines of code are covered, it helps in pointing out faulty code.
2. Branch Coverage:
In this technique, test cases are designed so that each branch from all decision points is traversed at least once. In a flowchart, all edges must be traversed at least once.
3. Condition Coverage
In this technique, all individual conditions must be covered as shown in the following example: 1. READ X, Y 2. IF(X == 0 || Y == 0) 3. PRINT ‘0’ 4. #TC1 – X = 0, Y = 55 5. #TC2 – X = 5, Y = 0
Tester should understand the code wellTester should write some code for test cases and execute themCode coverage analysis:White box testing helps to analyze the code coverage of an application, which helps to identify the areas of the code that are not being tested.Access to the source code:White box testing requires access to the application’s source code, which makes it possible to test individual functions, methods, and modules.Knowledge of programming languages:Testers performing white box testing must have knowledge of programming languages like Java, C++, Python, and PHP to understand the code structure and write tests.Identifying logical errors:White box testing helps to identify logical errors in the code, such as infinite loops or incorrect conditional statements.Thorough Testing: White box testing is thorough as the entire code and structures are tested.Code Optimization:It results in the optimization of code removing errors and helps in removing extra lines of code.Early Detection of Defects:It can start at an earlier stage as it doesn’t require any interface as in the case of black box testing.Integration with SDLC:White box testing can be easily started in Software Development Life Cycle.Programming Knowledge and Source Code Access:Testers need to have programming knowledge and access to the source code to perform tests.Overemphasis on Internal Workings:Testers may focus too much on the internal workings of the software and may miss external issues.Bias in Testing:Testers may have a biased view of the software since they are familiar with its internal workings.Test Case Overhead:Redesigning code and rewriting code needs test cases to be written again.Learn what white box testing is, how it differs from black box testing, and what techniques and tools are used for it. White box testing analyzes the internal structure and workings of a software application using source code and design documents.
Mar 18, 2024 · Learn the differences and benefits of white-box and black-box testing techniques in software development. White-box testing requires access to the source code and evaluates the internal flows, while black-box testing operates through the interface and verifies the functional and non-functional requirements.
Jul 25, 2023 · Black box testing checks the accuracy of your system without too much concern about the internal implementations. It identifies the interface-level bugs and resolves them. White box testing deeply scrutinizes and analyzes your system by checking its internal coding.
May 22, 2024 · Learn the definitions, differences and examples of black box testing and white box testing, two types of software testing based on functionality and structure. Compare the test objectives, techniques, test cases, test data, test coverage and roles of black box and white box testers.
