The Basics training focuses on using Test Macros, Parameters, and File IO. All testing is focused on verifying two simple routines:

 int sut_add(int x, int y);
 int sut_mult(int x, int y);

The routines are contained in software_under_test.c | h. The suggested things to Try will be focused on applying testing techniques on sut_mult().

Example option file my.opt used below for running

 --database "%STRIDE_DIR%\SDK\Windows\out\TestApp.sidb"
 --device TCP:localhost:8000

Test Macros

This Test Unit sample focuses on leveraging test macros when writing test cases. Note that it is not required to use test macros. A test case (method) can simply return a value to indicate pass or fail.

The following articles are related to this example:

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

First thing to do is run the TestMacros Test Unit. Start the TestApp.exe and use the following command:

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

You can take a look at the results by opening the generated stride.html in your browser.

Consider the following for TryStuff:

  • Add test code for the sut_mult() routine (remember to remove the set status call)
  • Add an Assert macro (verses an Expect). Do you understand the difference?
  • Throw in a Note macro .. provides more viability to the test logic
  • Change the test method documentation (in testmacros.h) and see how it shows up automatically in the test report
  • Change the test method name

Parameters

This Test Unit sample focuses on using parameters when writing test cases. Note that this sample has been implemented to (i) ensure parameters have been passed and (ii) support two different techniques for passing in parameters.

The following articles are related to this example:

The Test Unit is called TestParameters and is implemented in two source files: testparameters.cpp and testparameters.h. The comments and descriptions are contained in the header file. Two test cases are already implemented and one test method that can be used to make changes to is called TryStuff. Currently the TryStuff test method is set to not in use.

First thing to do is run the TestParameters Test Unit. Start the TestApp.exe and use the following command:

 stride --options_file my.opt --run "TestParameters(10,10)"

You can take a look at the results by opening the generated stride.html in your browser.

Now run a second time and use a file with INI-formatted input:

 stride --options_file my.opt --run "TestParameters(%STRIDE_DIR%/samples/testparameters.ini)"

Consider the following for TryStuff:

  • Add test code for sut_mult() using arguments from the command line
  • Add test code for sut_mult() using your own created ini file
  • Change the content of the ini file .. re-run the Test Unit

File IO

This Test Unit sample focuses on reading content from a host file to be used by the executing test logic. Note that this sample uses the srTest base class.

The following articles are related to this example:

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

The Test Unit is using an INI file (stride/samples/testfileio.ini) to indicate what input file content to use:

 ## Required parameters used for testing file IO
 ## Using groups

 [add]
 File = %STRIDE_DIR%/samples/testfileio.input.add
  
 [mult]

The corresponding add input file contains the following (note that the third column equals the sum):

 1,2,3
 5,6,11
 53,27,80

First thing to do is run the TestFileIO Test Unit. Start the TestApp.exe and use the following command:

 stride --options_file my.opt --run "TestFileIO(%STRIDE_DIR%/samples/testfileio.ini)"

You can take a look at the results by opening the generated stride.html in your browser.

Consider the following for TryStuff:

  • Add test code for sut_mult() using a different input file
  • Update the testfileio.ini file to include a second file for input
