Function Documentation

void gmx::test::callAddGlobalTestEnvironment ( )

This constructs the test environment during setup of the unit test so that they can use the hardware context.

Implement a stub definition for tests that don't ask for a real one.

Declare a function that all unit test implementations can use to set up any environment that they need.

When registering the unit test in CMake, the HARDWARE_DETECTION flag requires that the code for that unit test implements this function. Otherwise, a default stub implementation is provided.

This approach conforms to the recommendation by GoogleTest to arrange for the code that sets up the global test environment to be called from main, rather than potentially rely on brittle static initialization order.

template<typename T >
ArrayRef<char> gmx::test::charArrayRefFromArray ( T *  data,
size_t  size 
)

Convenience function to transform a view into one with base type of (non-const) char.

This transformation is useful for using containers with C APIs where the function signature is not declared const even where the semantics of the usage actually are const.

Parameters
[in]dataThe data pointer.
[in]sizeThe size of the data pointer (in T).
Template Parameters
TThe base type of the container
void gmx::test::checkConfFile ( TextInputStream *  input,
TestReferenceChecker *  checker,
const ConfMatchSettings &  settings 
)

Adds content of a gro file to TestReferenceChecker object.

Parameters
[in]inputStream that provides the gro content.
[in,out]checkerChecker to use.
[in]settingsSettings to use for matching.

Parses a gro file from the input stream, and checks the contents against reference data (only first two lines for now).

See Also
ConfMatch
void gmx::test::checkEnergiesAgainstReferenceData ( const std::string &  energyFilename,
const EnergyTolerances &  energiesToMatch,
TestReferenceChecker *  checker 
)

Check a subset of the energies found in an energy file against reference data.

Opens the energy file, loops over all frames, matching the indicated energies against refdata at the given tolerance.

Parameters
[in]energyFilenameThe name of an energy file.
[in]energiesToMatchSet of energies to match at given tolerances.
[in]checkerRoot checker for reference data.
Todo:
This is quite similar to the functionality used in PmeTest, and we should consider reducing the duplication.
void gmx::test::checkXvgFile ( TextInputStream *  input,
TestReferenceChecker *  checker,
const XvgMatchSettings &  settings 
)

Adds content of xvg file to TestReferenceChecker object.

Parameters
[in]inputStream that provides the xvg content.
[in,out]checkerChecker to use.
[in]settingsSettings to use for matching.

Parses an xvg file from the input stream, and checks the contents against reference data. settings can be used to customize the matching. Only a single data set is supported (but multiple columns work). A subset of xmgrace formatting is also checked; static content that is nearly always the same is skipped.

See Also
XvgMatch
static void gmx::test::compareBox ( const TrajectoryFrame &  reference,
const TrajectoryFrame &  test,
const TrajectoryFrameMatchSettings &  matchSettings,
const FloatingPointTolerance  tolerance 
)
static

Compares the box from reference and test according to the matchSettings and tolerance.

Todo:
This could be streamlined when we have a proper 3D matrix class and view.
void gmx::test::compareEnergyFrames ( const EnergyFrame &  reference,
const EnergyFrame &  test,
const EnergyTolerances &  tolerances 
)

Compare all fields of reference with all matching fields from test.

Ignore any key found in either reference or test that is not found in the other. For all keys found in both frames, compare the values with EXPECT_REAL_EQ_TOL and the given tolerance for that key.

void gmx::test::compareTrajectoryFrames ( const TrajectoryFrame &  reference,
const TrajectoryFrame &  test,
const TrajectoryFrameMatchSettings &  matchSettings,
const TrajectoryTolerances &  tolerances 
)

Compare the fields of the two frames for equality given the matchSettings and tolerances.

The two frames are required to have valid and matching values for time and step. According to matchSettings, box, positions, velocities and/or forces will be compared between frames, using the tolerances. Comparisons will only occur when both frames have the requisite data, and will be expected to be equal within the matching component of tolerances. If a comparison fails, a GoogleTest expectation failure will be given. If a comparison is required by matchSettings but cannot be done because either (or both) frames lack the requisite data, descriptive expectation failures will be given.

void gmx::test::done_enxframe ( t_enxframe *  fr)

Helper function to clean up resources.

Helper function to free resources (NB free_enxframe only frees the contents, not the pointer itself)

void gmx::test::done_trxframe ( t_trxframe *  fr)

Helper function to clean up resources.

Helper function to free all resources.

testing::Matcher< std::tuple< double, double > > gmx::test::DoubleEq ( const FloatingPointTolerance &  tolerance)

Make matcher for doubles for use with GoogleMock that compare equal when tolerance is satisifed.

Used like

EXPECT_THAT(testDoubles, Pointwise(DoubleEq(tolerance), referenceDoubles));

testing::Matcher< std::tuple< float, float > > gmx::test::FloatEq ( const FloatingPointTolerance &  tolerance)

Make matcher for floats for use with GoogleMock that compare equal when tolerance is satisifed.

Used like

EXPECT_THAT(testFloats, Pointwise(FloatEq(tolerance), referenceFloats));

template<typename Map >
std::vector<std::string> gmx::test::getKeys ( const Map &  m)

Convenience function to get std::string keys from a map.

This function can be used to provide an input for openEnergyFileToReadFields().

Todo:
This returns a copy of the keys, which is convenient, but inefficient. Alternatively, this could return a view of the keys from a range rather than a container, but there's no implementation of that in C++11 at the moment.
bool gmx::test::isNumberOfPpRanksSupported ( const std::string &  simulationName,
int  possibleNumberOfPpRanks 
)

Return whether the number of ranks is supported by the simulation simulationName in the database.

This method lets test runners understand when end-to-end tests should be expected to work.

EnergyFrameReaderPtr gmx::test::openEnergyFileToReadFields ( const std::string &  filename,
const std::vector< std::string > &  requiredEnergyFieldNames 
)

Open the file and return an object that can read the required fields from frames of an .edr file.

Parameters
[in]filenameName of the energy file to use
[in]requiredEnergyFieldNamesNames of the energy fields that the caller requires to be present for an .edr file frame to be considered valid
Exceptions
FileIOErrorIf the .edr file cannot be opened
APIErrorIf any required energy field is not present in the file
std::bad_allocWhen out of memory

This function is intended to have the main responsibility for making EnergyFrameReader objects.

void gmx::test::pmePerformSplineAndSpread ( gmx_pme_t *  pme,
CodePath  mode,
bool  computeSplines,
bool  spreadCharges 
)

PME spline calculation and charge spreading.

PME spline computation and charge spreading.

void gmx::test::pmeSetGridLineIndices ( const gmx_pme_t *  pme,
CodePath  mode,
const GridLineIndicesVector &  gridLineIndices 
)

Setting gridline indices to be used in spread/gather.

Setting gridline indices be used in spread/gather.

void gmx::test::pmeSetSplineData ( const gmx_pme_t *  pme,
CodePath  mode,
const SplineParamsDimVector &  splineValues,
PmeSplineDataType  type,
int  dimIndex 
)

Setting atom spline values/derivatives to be used in spread/gather.

Setting atom spline values or derivatives to be used in spread/gather.

MdpFieldValues gmx::test::prepareMdpFieldValues ( const char *  simulationName,
const char *  integrator,
const char *  tcoupl,
const char *  pcoupl 
)

Set up values for an .mdp file that permits a highly reproducible simulation.

An internal database of several kinds of simulation useful for such comparisons is available, whose simulationName keys are

  • argon12
  • argon5832
  • spc5
  • spc216
  • alanine_vsite_vacuo
  • alanine_vsite_solvated
  • glycine_vacuo
  • glycine_no_constraints_vacuo
  • nonanol_vacuo

Some of these systems are pretty minimal, because having few atoms means few interactions, highly reproducible forces, and allows tests to focus on the correctness of the implementation of high-level mdrun features. The boxes are of a reasonable size so that domain decomposition is possible. The pressure-coupling parameters are isotropic, and set up so that there will not be dramatic collapse of volume over the handful of MD steps that will be run. A single temperature-coupling group is used.

Parameters
[in]simulationNameThe name of the simulation, which indexes the database
[in]integratorThe integrator to use
[in]tcouplThe temperature-coupling algorithm to use
[in]pcouplThe pressure-coupling algorithm to use
Returns
Mdp file values
Exceptions
std::bad_allocif out of memory std::out_of_range if simulationName is not in the database
std::string gmx::test::prepareMdpFileContents ( const MdpFieldValues &  mdpFieldValues)

Make a string containing an .mdp file from the mdpFieldValues.

Exceptions
std::bad_allocif out of memory
static std::vector<RVec> gmx::test::putAtomsInBox ( const TrajectoryFrame &  frame)
static

Help put all atom positions in frame into its box.

This can perhaps go away when frame->x is a container.

testing::Matcher< std::tuple< real, real > > gmx::test::RealEq ( const FloatingPointTolerance &  tolerance)

Make matcher for reals for use with GoogleMock that compare equal when tolerance is satisifed.

Used like

EXPECT_THAT(testReals, Pointwise(RealEq(tolerance), referenceReals));

testing::Matcher< std::tuple< RVec, RVec > > gmx::test::RVecEq ( const FloatingPointTolerance &  tolerance)

Make matcher for RVecs for use with GoogleMock that compare equal when tolerance is satisifed.

Used like

EXPECT_THAT(testRVecs, Pointwise(RVecEq(tolerance), referenceRVecs));

static void gmx::test::throwIfNonEmptyAndOnlyWhitespace ( const std::string &  s,
const char *  id 
)
static

Throw a TestException if the caller tries to write particular refdata that can't work.

If the string to write is non-empty and has only whitespace, TinyXML2 can't read it correctly, so throw an exception for this case, so that we can't accidentally use it and run into mysterious problems.

Todo:
Eliminate this limitation of TinyXML2. See e.g. https://github.com/leethomason/tinyxml2/issues/432
