Is static testing black box testing?
Static testing is a stage of White Box Testing called dry run testing. Testing a program does not require a computer, for example reviewing, walk-through, inspection, etc.
Disadvantages / Cons of Black Box Testing
Test cases are extremely difficult to be designed without clear and concise specifications. Testing every possible input stream is not possible because it is time-consuming and this would eventually leave many program paths untested. Results might be overestimated at times.
| Advantages | Disadvantages |
|---|---|
| Well suited and efficient for large code segments. | Limited coverage, since only a selected number of test scenarios is actually performed. |
| Code access is not required. | Inefficient testing, due to the fact that the tester only has limited knowledge about an application. |
The correct answer is option 1. S1: Black-box tests are based on specifications; better at telling whether the program meets specification, better at finding errors of omission. Hence the statement I is False.
- Early detection and correction of any coding errors.
- Reduced cost in the early stages of development based on the amount of rework needed to fix any errors.
- Reduced time scales for development.
- Feedback received at this stage will help improve the overall software function.
Static testing is performed for the following reasons: We can find and address defects and errors early on. It improves development productivity. It reduces testing costs and the timeline for dynamic testing later on.
Incorrect or missing function. Interface errors. Errors in data structures or external database access. Behavior or performance errors.
The most common defects identified by the black box testing are access errors, interface errors, data errors, and missing functions.
- behavioral errors.
- logic errors.
- performance errors.
- typographical errors.
- b and d.
The best thing about Black box testing is that it can be applied to all levels of testing ( Unit, integration, system, and acceptance). Anybody with minimum or no coding language can perform Black box testing of a software product, software testers with no coding language can also do it.
Why is black box testing recommended?
Black box testing can be used to check if a new version of the software exhibits a regression, or degradation in capabilities, from one version to the next.
Lack of flexibility: The major disadvantage of a black box model is its lack of flexibility. If the model needs to be changed to describe something physically only slightly different, it can mean a lot of work to determine any new rules or bulk parameters.
Black box testing involves testing a system with no prior knowledge of its internal workings. A tester provides an input, and observes the output generated by the system under test.
Static Testing is a type of a Software Testing method which is performed to check the defects in software without actually executing the code of the software application. Whereas in Dynamic Testing checks, the code is executed to detect the defects.
There are various techniques used in black box testing for testing like decision table technique, boundary value analysis technique, state transition, All-pair testing, cause-effect graph technique, equivalence partitioning technique, error guessing technique, use case technique and user story technique.
White box testing is the dynamic testing type where the tester has knowledge of the source code and tests it by executing the code. This type of testing is also known as clear-box or glass-box testing.
