#include <testutils/include/testutils/cmdlinetest.h>
Helper class for tests that construct command lines that need to reference existing files.
This class provides helper methods for:
All files created during the test are cleaned up at the end of the test.
All methods can throw std::bad_alloc.

explicit |
Initializes an instance.
fileManager | File manager to use for generating temporary file names and to track temporary files. |
void gmx::test::CommandLineTestHelper::checkOutputFiles | ( | TestReferenceChecker | checker | ) | const |
Checks output files added with setOutputFile() against reference data.
checker | Reference data root location where the reference data is stored. |
The file contents are tested verbatim, using direct string comparison. The text can be found verbatim in the reference data XML files for manual inspection.
Generates non-fatal test failures if some output file contents do not match the reference data.

Runs a command-line program that implements ICommandLineModule.
[in,out] | module | Module to run. The function does not take ownership. |
[in,out] | commandLine | Command line parameters to pass. This is only modified if module modifies it. |
unspecified | Any exception thrown by the module. |

void gmx::test::CommandLineTestHelper::setInputFileContents | ( | CommandLine * | args, |
const char * | option, | ||
const char * | extension, | ||
const std::string & | contents | ||
) |
Generates and sets an input file.
[in,out] | args | CommandLine to which to add the option. |
[in] | option | Option to set. |
[in] | extension | Extension for the file to create. |
[in] | contents | Text to write to the input file. |
Creates a temporary file with contents from contents
, and adds option
to args
with a value that points to the generated file.
void gmx::test::CommandLineTestHelper::setInputFileContents | ( | CommandLine * | args, |
const char * | option, | ||
const char * | extension, | ||
const ArrayRef< const char *const > & | contents | ||
) |
Generates and sets an input file.
[in,out] | args | CommandLine to which to add the option. |
[in] | option | Option to set. |
[in] | extension | Extension for the file to create. |
[in] | contents | Text to write to the input file. |
Creates a temporary file with contents from contents
(each array entry on its own line), and adds option
to args
with a value that points to the generated file.
std::string gmx::test::CommandLineTestHelper::setOutputFile | ( | CommandLine * | args, |
const char * | option, | ||
const char * | filename, | ||
const ITextBlockMatcherSettings & | matcher | ||
) |
Sets an output file parameter and adds it to the set of tested files.
[in,out] | args | CommandLine to which to add the option. |
[in] | option | Option to set. |
[in] | filename | Name of the output file. |
[in] | matcher | Specifies how the contents of the file are tested. |
This method does the following:
option
to args
to point a temporary file name constructed from filename
.matcher
.filename
is given to TestTemporaryFileManager to make a unique filename for the temporary file. If filename
starts with a dot, a unique number is prefixed (such that it is possible to create multiple files with the same extension by just specifying the extension for every call of setOutputFile()).
If the output file is needed to trigger some computation, or is unconditionally produced by the code under test, but the contents are not interesting for the test, use NoContentsMatch as the matcher. Note that the existence of the output file is still verified.
std::string gmx::test::CommandLineTestHelper::setOutputFile | ( | CommandLine * | args, |

std::string gmx::test::CommandLineTestHelper::setOutputFileWithGeneratedName | ( | const char * | filename, |
const ITextBlockMatcherSettings & | matcher | ||
) |
As for setOutputFile()
but does not create an option.
This method is useful when a tool generates a series of output files by modifying a common base name. Call this method with every file name that is expected to be generated by the tool. It returns the name of the output file
