===What is Test Fixturing?===
+
Refer to [[Test Point Testing in C/C++|this article]].
Recall that  generic xUnit testing comprises four discrete phases:
 
# Setup
 
# Exercise
 
# Verify
 
# Teardown
 
  
''Test fixturing'' refers to the Setup and Teardown  phases of the testing.
+
== Test Fixturing ==
 
 
In the '''Setup'''  phase, we put all of the things into place that are required in order  to run a our test and expect a particular outcome. This includes things  like:
 
* Acquiring resources such as memory,  hardware, etc.
 
* Setting up required states such as input  files in place, memory filled with a pattern, dependencies initialized,  etc.
 
 
 
In the '''Tear down'''  phase, we clean up the fixturing we did in the Setup phase, leaving the  system in a state that is ready to be used by the next test.
 
 
 
===The Importance of  Fixturing===
 
The proper use of  fixturing can simplify test writing and lead to these benefits:
 
 
 
* Separation of  initialization/deinitialization code from your test code
 
* Reuse of  setup and teardown code within a test unit
 
* Simplification  of resource cleanup in test methods
 
 
 
===STRIDE Fixturing  Resources===
 
====Specifying  Fixturing Methods====
 
Within  your source code, you can optionally specify '''setup'''  and '''teardown''' methods using the [[Test Unit Pragmas|scl pragmas]]:
 
 
 
*[[Scl test setup|scl_test_setup()]]
 
*[[Scl test teardown|scl_test_teardown()]]
 
 
 
When  declaring these pragmas, you specify 1) the test unit the pragma  applies to; and 2) the name of the method that will be called by the  STRIDE framework to perform the Setup or Teardown fixturing. If  specifed, the STRIDE framework will call the Setup method before each  test method in the test unit, and the Teardown method after each test  method in the test unit.
 
 
 
You can see examples of fixturing  delcarations in these test samples:
 
*[[Test Class Samples]]
 
*[[Test CClass Samples]]
 
 
 
====Advanced  Fixturing====
 
A common test  pattern--especially in the area of multimedia--is to create a test that  is parametrized by an input file. The test is run multiple times with a  different input file used for each run.
 
  
In this case the setup  fixturing makes the file data available to the test (typically opening a  file on the host, then copying data from host to target), and the  teardown fixturing removes any files created on the target and so forth.
+
Refer to [[Test Fixturing in C/C++|this article]].
 
 
STRIDE  offers an integrated solution to file fixturing that makes it possible  from your target test code to specify a host-based file and transfer its  data to the target. Refer to the [[File_Services_Samples  | File  Services Samples]] that demonstrates techniques and  syntax for performing basic tasks using the [[File Transfer  Services|File Transfer Services API]].
 
  
 
== Test Documentation ==
 
== Test Documentation ==
The STRIDE  Framework provides an integrated solution for automatically extracting  documentation for your test units using the well-known [http://www.stack.nl/~dimitri/doxygen/ doxygen format]. In order to enable test unit  documentation, here is summary of the necessary steps:
 
* document your test unit source with [http://www.stack.nl/~dimitri/doxygen/docblocks.html doxygen] formatted blocks. Since only header files  are typically passed to the [[S2scompile|stride  compiler]], we recommend you place your  documentation in the header file. Alternatively, if you have an  implementation (c or cpp) file with the same basename located in the  same directory as your header file, we will search this file for  documentation as well.
 
* configure your build/make process to call  the [[S2scompile|stride compiler]] with the additional '''--documentation''' flag. If you are using one of our  preconfigured makefiles in a sandbox environment, this option has  already been enabled.
 
* run your build process to produce a stride  database and stride enabled target application.
 
* start your  application and execute the [[Stride_Runner|stride runner]]  to connect and run the tests.
 
* The generated report will contain  description information for the test suites and test cases generated  from the doxygen blocks.
 
  
=== Recommendations and Guidelines ===
+
Refer to [[Test Documentation in C/C++|this article]].
As mentioned above, we generally  recommend that you document your test units in the header file so as to  ensure that the stride toolchain is able to properly correlate test  units with the extracted documentation. For simplicity, we also  recommend that you place your documentation blocks as close as possibly  to the documented entity (class, struct, or method) so as to avoid  confusion. The following are specific notes about documenting each of  the three types of test units that the STRIDE Framework supports.
 
  
==== Test Classes ====
+
== Runtime  Test Services  ==
Source documentation is  generally straight-foward, with doc blocks preceding the corresponding  class and method declaration. If you prefer to locate your documentation  blocks elsewhere in the header file, use the '''\class'''  tag to correlate your docs and declared test class.
 
  
==== Test C-Classes ====
+
Refer  to [[Runtime Test Services|this article]] for a complete listing of the Runtime Test Services APIs.
Source documentation must relate to the structure that is used as the "C-Object" for the test unit.  Since a C-Class uses function pointers to call its individual tests,  test method documentation '''must'''  be associated with the corresponding structure function pointer member.  As such, method documentation for C-Classes must be in the header file.
 
  
==== Test FLists ====
+
== File Transfer Services ==
Since FLists have no specific  storage entity (class or struct) to which they are associated. As such,  the only way to provide unit-level documentation for FLists is to  document the source file in which its methods are declared. The unit  documentation is associated with its file using the '''\file''' tag. Because of this restriction,  you will only be able to provide documentation for one FList in each  header file - so we recommend that you generally confine each Test FList  to it's own source file pair (.h and .c). The test methods associated  with an FList are documented as expected, with the documentation block  preceding the function declaration.
 
  
=== Supported Doxygen Tags ===
+
Refer to [[File Transfer Services|this article]] for a complete listing of the File Transfer Services APIs.
 
 
Doxygen has a rich set of tags  and formatting options aimed at comprehensive source documentation. The  STRIDE Framework uses doxygen on a per-file basis to extract standalone  documentation for individual test units and their methods. As such, we  only support limited set of doxygen features in the code documentation.  The STRIDE Framework supports the following doc formatting:
 
* custom HTML formatting
 
* lists  (ordered, unordered, definition)
 
* code blocks
 
* bold and  emphasis text
 
More advanced doxygen formatting tags  (such as tables and parameter lists) are not supported at this time, but  will likely be in future releases.
 
 
 
For more information on  Doxygen formatting, see [http://www.doxygen.nl/docblocks.html]
