This article mainly introduces "what tests C++ Test has". In daily operation, I believe many people have doubts about what test problems C++ Test has. Xiaobian consulted various materials and sorted out simple and easy operation methods. I hope to help you answer the doubts of "what tests C++ Test has"! Next, please follow the small series to learn together!

C++Test automatically builds a test driver designed to maximize test coverage and error detection for classes. To create a test driver for a class, you simply open the class and press the Build Test key. C++Test will automatically build the test driver.

In addition, C++Test can automatically generate stub functions if the method under test calls functions that do not exist or are inaccessible at the time; this tests interactions with external resource operations and does not contain any hidden weaknesses. C++Test does not actually call these functions, but rather calls stub functions and returns the values provided by the stub functions.

If you need to control the use of return values, you can build a pile call table that lives the input/output relationships. You can also add user-defined stub functions. For example, if you want to use the original function, and the function is defined in a different file; or if you want to simulate the behavior of the original function, and replace it with a simple function to automatically generate C/C++ class test drivers and stub functions is unique to C++Test;

Only C++Test can automatically test a C/C++ class (once it can compile) without any user intervention. This enables you to automatically detect code errors as quickly as possible, finding and correcting them in the easiest, cheapest and fastest way. Without such automation tools, significant time and resource consumption would negate the potential benefits and practical significance of unit testing.

static test

C++Test embeds more than 700 C/C++ specifications such as the industry's most famous Effective C++(epcc), More Effective C++(mepcc), meyer-klaus(mk), and Universal Code Standard(ucs), and users can customize their own specifications.

It also integrates specifications accumulated by parasoft. In static testing, C++Test will scan the code thoroughly to verify whether there are conflicts with these specifications, and find some simple or low-level errors as soon as possible to avoid the integration spread caused by them.

white-box testing

C++Test provides an effective and efficient way to perform white-box testing. C++Test fully automates all white-box testing processes, automatically generating and executing well-designed test cases. Any run failures are automatically flagged and displayed in a simple graphical structure. These test cases are then automatically saved and can be easily used for later regression testing.

Because C++Test can automatically generate stub functions, or allow you to add your own stub functions, it can test classes that reference external objects. In other words, C++Test can run any class or set of classes and automatically generate and execute a set of test cases designed to find as many errors as possible. C++Test allows you to customize the generation of white-box test cases and at what level (project, file, class, or method) tests are executed.

black box testing

C++Test eases the burden of black-box testing by automating most of its operations. In particular, there are two ways to automate the *** phase of black box testing-building test cases:

·Helps you set the results for each test case.

You can simply enter the test case input and let C++Test run the test case and automatically determine the actual output. If the result is correct, no further action is required. If the result is incorrect, you can enter the expected output. This is faster and easier than manually entering results for each test case. Automatically generate a core set of test cases.

C++Test automatically designs a broad spectrum of white-box test cases. When using these test cases in black box testing, you simply observe the actual output results and enter the expected values for any incorrect results.

When you need to enter or modify test cases.

You can simply type in the values in the test case framework automatically generated by C++Test. This will significantly speed up the process of building test cases. In addition to automating most of the steps of building black box test cases, C++Test completely automates the remaining black box test steps. With the press of a key, you can run one or a group of projects, files, classes, or methods. C++Test then automatically executes all test cases, reports all input/output relationships, and flags any test cases where the actual output does not match expectations or causes the program to crash.

regression testing

C++Test completely automates all steps related to regression testing. C++Test** When testing a class, automatically save its tests and test parameters. When it comes time to perform regression testing, you can open the appropriate project and file and run all the original white-box and black-box test cases;C++Test will automatically run the exact same test cases and test parameters and inform them of any problems found. This means that you can immediately know if the modification introduced any errors.

monitoring test coverage

To help you measure the effectiveness of the currently used test case set and give you information to achieve the highest possible coverage, C++Test automatically monitors test coverage.

C++Test tracks coverage in real time and then creates a comprehensive test coverage report.

The coverage window graphically illustrates the lines of code currently being executed, the lines that have been executed, and the number of executions per line. Thus, it indicates not only whether a line of code has been tested, but how thoroughly it has been tested. This information can be very helpful in determining which code needs additional testing.

At this point, the study of "what tests C++ Test has" is over, hoping to solve everyone's doubts. Theory and practice can better match to help everyone learn, go and try it! If you want to continue learning more relevant knowledge, please continue to pay attention to the website, Xiaobian will continue to strive to bring more practical articles for everyone!
