The Advanced training focuses on using Test Doubles, Test Points, and Fixtures.

The Test Doubles will demonstrate how global functions can be dynamically intercepted and replaced with test logic (stub, fake, mock). The following routines will be used:

int sut_foo(int x);
int sut_boo(int x);
int sut_2xboo(int x);
int sut_strcheck(const char *s);

Test Points enable a different style of testing using source instrumentation. This is especially applicable when normal API testing is not practical. The following sequencing routines will be called that issue Test Points calls (again very simple but used to show the technique).

void sut_Sequence1(void);
void sut_Sequence2(void);
void sut_Sequence3(void);

Fixturing shows how setup and teardown routines per test method can be incorporated within a Test Suite. It will rely on the following routines to control thread:

void sut_start_thread(void);
void sut_stop_thread(void);

Test Doubles

This test suite focuses on leveraging Test Doubles in the context of executing a test.

The following articles are related to this example:

The Test Suite is called TestDoubles and is implemented in two source files: testdoubles.cpp and testdoubles.h. The comments and descriptions are contained in the header file. Three test cases (methods) are already implemented and one test method that can be used to make changes to called TryStuff. Currently this test method is set to not in use.

First thing to do is run the TestDoubles Suite. Start the TestApp.exe and use the following command:

 stride --options_file my.opt --run "TestDoubles"

You can take a look at the results in TestApp.xml.

Consider the following for TryStuff:

  • Create your own stub for foo() and intercept it
    • confirm it returns what you expect
  • Double sut_boo()
    • call sut_2xboo() with a number
    • confirm with a Test Macro within the double the passed in number (mocking example)

Test Points

This test suite focuses on Test Points and how to validate them.

The following articles are related to this example:

The Test Suite is called TestPoints and is implemented in two source files: testpoints.cpp and testpoints.h. The comments and descriptions are contained in the header file. Three test cases (methods) are already implemented and one test method that you can be used to make changes to called TryStuff. Currently this test method is set to not in use.

First thing to do is run the TestPoints Suite. Start the TestApp.exe and use the following command:

 stride --options_file my.opt --run "TestPoints"

You can take a look at the results in TestApp.xml.

Consider trying the following:

  • Write a test to validate a subset of Test Points
  • Write a test to validate "E", "F", and "G", and a predicate to verify data associated with "E"

Fixtures

This test suite focuses on using Fixutres in the context of an executing Test Suite.

The following articles are related to this example:

The Test Suite is called TestFixtures and is implemented in two source files: testfixtures.cpp and testfixtures.h. The comments and descriptions are contained in the header file. One test cases (methods) is already implemented and one test method that can be used to make changes to TryStuff. Currently this test method is set to not in use.

First thing to do is run the TestFixtures Suite. Start the TestApp.exe and use the following command:

 stride --options_file my.opt --run "TestFixtures"

You can take a look at the results in TestApp.xml.

Consider trying the following:
