MinGW Testsuite

Introduction

At the moment there is no automated method to check the state of the MinGW toolchain which is in Fedora. There's a good possibility that regressions get slipped in and only get discovered after some time.

To prevent these kind of issues we need to have an automated testsuite which can test various parts of the Fedora MinGW toolchain.

Such a testsuite can eventually be hooked in AutoQA so automated testing will be done automatically as soon as something is changed in one of the Fedora MinGW packages.

Requirements

• Must support both the current mingw.org-based toolchain as well as the new mingw-w64-based toolchain
• Must support both win32 as well as win64 binaries
• Must be able to run on Fedora 16 and above and RHEL6/CentOS6
• Must be easily extendable (without re-compilation of the testsuite tool)

Type of tests

RPM macros

• Goal: regression testing of the mingw-filesystem package
• Method: parse rpm code and make sure the parsed output is what we expect
• Input: text file containing rpm code which needs to be parsed
• Output: the parsed rpm code

Compile and runtime checks (single file)

• Goal: test the toolchain
• Method: testing if compilation of a .c / .cpp file succeeds without compiler warnings/errors
• Input: .ini file describing which .c / .cpp file should be used, any additional CFLAGS, boolean whether the binary should be executed using wine and expected output
• Output: gcc output, exit code of gcc, runtime output, runtime exit code

Custom script

• Goal: test the toolchain
• Method: call a custom script which can set the exit code to indicate whether the test has failed or succeeded
• Input: .ini file describing the script which needs to be executed and its command line parameters, the script which contains the testcase
• Output: the output of the script and its exit code

File format

A testcase always consists of one textfile which describes the testcase. This file is using the INI-file style for its contents and must have the suffix '.testcase' in order to be recognized by the testsuite tool.

Here's an example of such a testcase (the file shown is named macro_mingw32_configure.testcase):

[mingw_testcase]
type=rpm_parser
input_text=%{_mingw32_configure}
expected_output_file=mingw32_configure_output.txt

All testcases belonging to the Fedora MinGW Testsuite must contain a section named 'mingw_testcase' . In this section a key named 'type' is also required. The value belonging to this key can be used to identify the type of test which needs to be executed. At the moment the following types are valid:

• rpm_parser
• compile_and_run
• custom

Depending on the type of the testcase one or more additional key/value pairs need to be set

Type 'rpm_parser'

Testcases for the type 'rpm_parser' need to provide an input text and an output text. The input text is the RPM code which needs to be processed by the RPM parser. The output text is the RPM code as returned after being processed by the RPM parser. The testcase will be successful when the output from the RPM parser is the same at the expected output.

The following keys are supported:

• required: input_text - string - The RPM code which needs to be processed by the RPM parser
• required: input_file - string - A textfile containing the RPM code which needs to be processed by the RPM parser
• required: expected_output_text - string - The output which is expected
• required: expected_output_file - string - A textfile containing the output which is expected

Only one input key-value pair and one output key-value pair are required. It is recommended to use the '*_text' keys for single-line strings and the '*_file' keys for multi-lines.

Type 'compile_and_run'

The following keys are supported:

• required: source_file - string - The file name of the file which needs to be compiled
• required: run_binary - boolean - Whether this testcase only needs to compile the binary (false) or whether it needs to be compiled and executed (true)
• optional: cflags - string - Any additional CFLAGS which need to be used to compile this testcase
• optional: ldflags - string - Any additional LDFLAGS which need to be used to compile this testcase
• optional: expected_stdout_text - string - The stdout output which is expected when the binary is executed
• optional: expected_stdout_file - string - A textfile containing the stdout output which is expected when the binary is executed
• optional: expected_stderr_text - string - The stderr output which is expected when the binary is executed
• optional: expected_stderr_file - stirng - A textfile containing the stderr output which is expected when the binary is executed

Only one input key-value pair and one output key-value pair are required. It is recommended to use the '*_text' keys for single-line strings and the '*_file' keys for multi-lines.
