CC can be calculated with two types of formulae: a) M=E-N+2P b) M=E-N+P (For Strongly conn If the program has a high complexity number, then the probability of error is high with greater maintenance time and troubleshooting. It results in the optimization of code removing error and helps in removing extra lines of code. Is a useful software metric for structured or white-box testing. Download This Tutorial in PDF. Carry out the simple loop tests for the innermost loop, keeping the iteration values ​​of the outermost loops at the minimum values. ... (software testing), cyclomatic complexity dapat digunakan untuk menentukan berapa minimal test caseyang harus dijalankan untuk menguji sebuah program dengan menggunakan teknik basis path testing. It checks each linearly independent path through the program, which means number test cases, will be equivalent to the cyclomatic complexity of the program. Since here, e = 5 n = 4 and, P = 1 . Testers also indeed avoid a type of testing which they feel to be very complicated and the developer’s piece of cake. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account.

Learn different white box testing techniques and tools with examples. Edges Statements in a program are represented as nodes, and control paths from one statement to another are represented by Edges. White Box Testing. Basis path testing is a testing technique in White Box Testing method initially proposed by McCabe and allowing a test case designer to measure logic complexity from procedural design. An independent path is defined with reference to the succession of independent paths accumulated, that is : any path on the program flow graph that includes at least one edge that is not included in any of the former independent paths. Four different types of loops can be defined: The following set of tests must be applied to simple loops (of n iterations): If we extended the set of tests from simple loops to nested loops, the number of tests would grow geometrically, so Beizer suggests the following set of tests for nested loops: Test the concatenated loops using the test techniques for simple loops, considering them as independent loops. (Continued on next question...) Other Interview Questions How will you test the field that generates auto numbers of AUT when we click the button 'NEW" in the application? Thanks in advance.

Cyclomatic complexity of a program tells us the quantitative measure of the complexity of a program. Cyclomatic complexity is used to measure the complexity of a given program code. Test cases derived to exercise the basis set are guaranteed to execute every statement in the program at least one time. This practice was adopted by the NIST Structured Testing methodology, with an observation that since McCabe's original publication, the figure of 10 had received substantial corroborating evidence, but that in some circumstances it may be appropriate to relax the restriction and permit modules with a complexity as high as 15. One common testing strategy, espoused for example by the NIST Structured Testing methodology, is to use the cyclomatic complexity of a module to determine the number of white-box tests that are required to obtain sufficient coverage of the module. 5 : What types of errors are missed by black-box testing and can be uncovered by white-box testing ? 230 Yes : 45 No : Post New Answer View All Answers.
