Fundamentals of software Testing Day 1

software defects can be called software defects only if they conform to the following 5 rules

1. The software is to achieve the function indicated in the product specification.
2. The software has an error indicating that the product specification does not appear.
3. The software function is beyond the scope specified in the product specification.
4. The software does not meet the objectives stated in the product specification but should be achieved.
5. Software testers think software is difficult to understand, inappropriate to use, slow to run, or bad for end-user tasks.

The goal of software testers is to discover software defects  

Black box test and white box test

In black-box testing, software testers simply need to know what the software is doing--without seeing how the box works. With just a few inputs, you get some kind of output, he doesn't know how the software works, why it does that, just what the program does.

In white-box testing (sometimes referred to as an open-box test), software testers can access the programmer's code and check the code to assist in testing--you can see inside the box. The tester checks the results of the code to determine how large the number may be wrong and adjust the test program accordingly. Static and dynamic test static tests refer to parts of the test that are not running--just checks and reviews. Dynamic testing refers to the usual sense of testing-running and using software. Static black box test, test product Specification Test product specification is static test black box test, product specification is written document, not called executable program, so counted as static.
