Test Units Overview

Introduction

STRIDE enables testing of C/C++ code through the use of xUnit-style test units. Test units can be written by developers, captured using an SCL pragma, and executed from the host. STRIDE facilitates the execution of some or all of the test units by automatically creating entry points for the execution of test units on the target.

Using test units

Prerequisites

see Perl requirements.

How to get started (Overview)

The required steps to get started with writing test units are as follows:

Create a new Studio workspace (or open an existing one).
Set the workspace to compile in C++ mode (In Studio, choose Tools->Settings->Compile as Cpp).
Write a test unit. You may create a C++ test class or a C test function as your test unit. Click here for more information on creating test units.

#include <srtest.h>

class Simple {
public:
    int test1(void) { return  0;} // PASS
    int test2(void) { return 23;} // FAIL <>0
};

#pragma scl_test_class(Simple)

Or, as a test function:

#ifdef __cplusplus
extern "C" {
#endif

int test1(void) 
{
    return 0; // PASS
}

int test1(void) 
{
    return 23; // FAIL <>0
}

#pragma scl_test_flist("Simple", test1, test2)

#ifdef __cplusplus
}
#endif

Compile the workspace & review the Simple interface in the Studio Interface tab
Create a script to generate the Intercept Module(IM) after the compilation step.
For the simple STUB generation required for test unit execution, you can use the following code

use strict;
use Win32::OLE qw(in);
Win32::OLE->Option(Warn => 3);
my $intercept = $main::studio->Workspace->Intercept;    
$intercept->{Path} = $main::studio->Workspace->Path;
$intercept->{Name} = $main::studio->Workspace->Name;
map {$intercept->Item($_)->{Stub} = 1} (0..($intercept->Count - 1));
$intercept->Create();

Optionally add custom scripts to automate the building and executing your application. Refer to Using Frameworks for more information regarding building and executing tests with a target device.
Ensure that the Studio workspace include path contains the location to all of your test unit declaration (header) files.
Once you have created one or more test units, ensure the following:
- Workspace is compiled and saved
- Intercept Module is generated (Stubs for all Test Units)
- Target application re-built
- Target application downloaded & started
- STRIDE Connected to Target
If your application is running, you can start executing test units.
- You can test-execute individual test units interactively using the Studio interface view. To do this, open the user interface view corresponding to the test unit you would like to execute, then call it. The return values will indicate how many tests produced each of four (4) result types. Furthermore, the input to the entry point will allow you to select all methods for execution (the default) or individual methods via a dropdown list of enumerated values.
- Once you are confident that the test units are behaving as expected, you can generate one or more execution scripts using the Script Wizard. Sample templates for executing test unit entry points are provided in the %STRIDE_DIR%\templates\Script Wizard directory.
- When writing scripts to execute test units, the AutoScript TestUnits collection is a powerful tool for test unit execution and reporting, and for obtaining test results.
For integration with larger regression test workspaces, we recommend that developers check in their test unit code and, optionally, the template-generated scripts that can be used to execute their test units.

Pragmas for Test Units

STRIDE supports three pragmas for capturing and qualifying test units:

scl_test_class ( class-name ): Declares a test class as captured. Once captured, STRIDE will generate the appropriate code for executing the test methods in the class. See the scl_test_class page for more information.
scl_test_flist ( test-unit-name , test-function-name { , test-function-name } ): Declares a test unit as captured, by the specified test-unit-name. One or more functions (test methods) are associated with the test unit. Once captured, STRIDE will generate the appropriate code for executing the associated test methods. See the scl_test_flist page for more information.
scl_test_cclass ( struct-name , init-function-name { , deinit-function-name } ): Declares a test unit as captured. Once captured, STRIDE will generate the appropriate code for executing the associated test methods. See the scl_test_cclass page for more information.
scl_test_setup ( test-unit-name , method-name ): [optional] Declares a member method to be a setup fixture for the test unit. If specified, the setup method will be called before the execution of each test method. See the scl_test_setup page for more information.
scl_test_teardown ( test-unit-name , method-name ): [optional] Declares a member method to be a teardown fixture for the test unit. If specified, the teardown method will be called after the execution of each test method. See the scl_test_teardown page for more information.

Test Unit Requirements

Several variations on typical xUnit-style test units are supported. The additional supported features include:

Test status can be set using STRIDE Runtime APIs or by specifying simple return types for test methods.
Simple return types: 0 = PASS; <> 0 = FAIL
void return type with no explict status setting is assumed PASS
Test writers can create additional child suites and tests at runtime by using Runtime APIs.
We do not rely on exceptions for reporting of status.

The STRIDE test class framework has the following requirements of each test class:

The test class must have a suitable default (no-argument) constructor.
The test class must have one or more public methods suitable as test methods. Allowable test methods always take no arguments (void) and return either void or simple integer types (int, short, long, char or bool). At this time, we do not allow typedef types or macros for the return values specification.
the scl_test_class pragma must be applied to the class.

Simple example using return values for status

Using a Test Class

#include <srtest.h>
  
class Simple {
public:
    int tc_Int_ExpectPass(void) {return 0;}
    int tc_Int_ExpectFail(void) {return -1;}
    bool tc_Bool_ExpectPass(void) {return true;}
    bool tc_Bool_ExpectFail(void) {return false;}
};

#ifdef _SCL
#pragma scl_test_class(Simple)
#endif

Using a Test Function

#include <srtest.h>
  
#ifdef __cplusplus
extern "C" {
#endif
  
int tf_Int_ExpectPass(void) {return 0;}
int tf_Int_ExpectFail(void) {return -1;}
bool tf_Bool_ExpectPass(void) {return true;}
bool tf_Bool_ExpectFail(void) {return false;}

#ifdef _SCL
#pragma scl_test_flist("Simple", tf_Int_ExpectPass, tf_Int_ExpectFail, tf_Bool_ExpectPass, tf_Bool_ExpectFail)
#endif
   
#ifdef __cplusplus
}
#endif

Simple example using runtime test service APIs

Using a Test Class

#include <srtest.h>
  
class RuntimeServices_basic {
public: 
  void tc_ExpectPass(void) 
  {
    srTestCaseAddComment(srTEST_CASE_DEFAULT, "this test should pass");
    srTestCaseSetStatus(srTEST_CASE_DEFAULT, srTEST_PASS, 0); 
  }
  void tc_ExpectFail(void) 
  {
    srTestCaseAddComment(srTEST_CASE_DEFAULT, "this test should fail");
    srTestCaseSetStatus(srTEST_CASE_DEFAULT, srTEST_FAIL, 0); 
  }
  void tc_ExpectInProgress(void) 
  {
    srTestCaseAddComment(srTEST_CASE_DEFAULT, "this test should be in progress");
  }
};

#ifdef _SCL
#pragma scl_test_class(RuntimeServices_basic)
#endif

Using a Test Function

#include <srtest.h>
  
#ifdef __cplusplus
extern "C" {
#endif
  
void tf_ExpectPass(void) 
{
  srTestCaseAddComment(srTEST_CASE_DEFAULT, "this test should pass");
  srTestCaseSetStatus(srTEST_CASE_DEFAULT, srTEST_PASS, 0); 
}
void tf_ExpectFail(void) 
{
  srTestCaseAddComment(srTEST_CASE_DEFAULT, "this test should fail");
  srTestCaseSetStatus(srTEST_CASE_DEFAULT, srTEST_FAIL, 0); 
}

}

#ifdef _SCL
#pragma scl_test_flist("RuntimeServices_basic", tf_ExpectPass, tf_ExpectFail, tf_ExpectInProgress)
#endif
 
#ifdef __cplusplus
}
#endif

Simple example using srTest base class

#include <srtest.h>
  
class MyTest : public stride::srTest {
public:
  void tc_ExpectPass(void) 
  {
    testCase.AddComment("this test should pass");
    testCase.SetStatus(srTEST_PASS, 0); 
  }
  void tc_ExpectFail(void) 
  {
    testCase.AddComment("this test should fail");
    testCase.SetStatus(srTEST_FAIL, 0); 
  }
  void tc_ExpectInProgress(void) 
  {
    testCase.AddComment("this test should be in progress");
  }
  int tc_ChangeMyName(void) 
  {
    testCase.AddComment("this test should have name = MyChangedName");
    testCase.SetName("MyChangedName");
    return 0;
  }
  int tc_ChangeMyDescription(void) 
  {
    testCase.AddComment("this test should have a description set");
    testCase.SetDescription("this is my new description");
    return 0;
  }
};

#ifdef _SCL
#pragma scl_test_class(MyTest)
#endif

Runtime Test Services

The Runtime Test Services (declared in srTest.h) are a set of APIs in the STRIDE Runtime that facilitate the writing of target based test code. These APIs make up an optional portion of the STRIDE Runtime and can be used to communicate additional information about tests to the host based reporting mechanism. These APIs also allow target test code to create additional test suites and test cases dynamically at runtime.

There are 2 alternate ways of accessing these APIs: through C-based functions, or through a C++ base class from which you may derive your C++ test class. These are discussed below in C Test Functions, and C++ Test Classes sections below.

C++ Test Classes

The Runtime Test Services C APIs work equally well from C test functions and C++ test classes. If, however, you are using C++ it might be more convinient for you to derive your C++ test classes from the Runtime Test Services C++ base class, srTest. That way you will have access to a set of simpler to use C++ classes.

The following C++ classes are provided:

class srTest - base test class
class srTestSuite - represents a test suite
class srTestCase - represents a test case
class srTestAnnotation - represents a test annotation

class srTest

The srTest class provides two Member Objects:

testSuite of class srTestSuite
testCaseof class srTestCase

class srTestSuite

The srTest class provides the folowing methods:

Refer to the SCL Reference Guide or the Runtime Developer's Guide for detailed information about any of these APIs.

Scripting a Test Unit

To automate the execution and reporting of a Test Unit a script is required. Scripts can be written by hand or automatically generated using the Script Wizard and a corresponding template script. A scripting tool for executing a test unit is the AutoScript TestUnits collection. An Ascript TestUnit object assembles all of the reporting information for the test unit and its corresponding test methods.

Require useage of the AutoScript TestUnits collection
Can be written by hand (refer below)
Can leverage Templates via the Script Wizard
Order of multiple test units dictated by SUID assignment

JScript example for a single test unit

The following example script is used to harness a test unit that has been captured using #pragma scl_test_class(Simple).

// Ensure test unit exists
if (ascript.TestUnits.Item("Simple") != null) 
  ascript.TestUnits.Item("Simple").Run();

Perl example for a single test unit

The following example script is used to harness a test unit that has been captured using #pragma scl_test_class(Simple).

use strict;
use Win32::OLE;
Win32::OLE->Option(Warn => 3);
   
my $tu = $main::ascript->TestUnits->Item("Simple");
if (defined $tu) {
  $tu->Run();
}

JScript example for multiple test units

The following example script is used to harness two test units that have been captured using #pragma scl_test_class(Simple1) and #pragma scl_test_class(Simple2).

var Units = ["Simple1","Simple2"];
  
// iterate through each function
for (i in Units)
{
  var tu = ascript.TestUnits.Item(Units[i]);
  if ( tu&nbsp;!= null ) 
    tu.Run();
}

Perl example for multiple test units

The following example script is used to harness two test units that have been captured using #pragma scl_test_class(Simple1) and #pragma scl_test_class(Simple2).

use strict;
use Win32::OLE;
Win32::OLE->Option(Warn => 3);
   
# initialize an array with all selected function names
my @UnitNames = ("Simple1","Simple2");
foreach (@UnitNames) {   
  my $tu = $main::ascript->TestUnits->Item($_->[1]);
  die "TestUnit not found: $_->[1]\n" unless (defined $tu);
  $tu->Run();
}
