Member Function Documentation

run()

void toolbox::particles::assignmentchecks::tests::TestHelpers::run ( )

overridevirtual

This routine is triggered by the TestCaseCollection.

Implements tarch::tests::TestCase.

Definition at line 2226 of file TestHelpers.cpp.

References testMethod.

testAddingParticleEvents()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testAddingParticleEvents ( )

private

Test the adding of particle events to the database.

This also serves as a unit test for all possible events: I let the particles run through some meaningless mesh sweeps, and add all the event types.

Here, I only use static particles, so the identifier remains the same all the time. Switching particle identifiers will be done in a separate test. We're also adding events without them having any meaning. Proper event tracing including consistency checks will also be done later.

testAddingParticleMovingEvents()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testAddingParticleMovingEvents ( int nsweeps = 100, int nEventsToKeep = 1000 )

private

Test the adding of particle events to the database with a moving particle.

The catch is twofold: Firstly, the fuzzy search needs to work. Secondly, a moving particle will eventually need to change its identifier in the database. This tests both of these cases, but not the event deletion when the database becomes too large.

We're also adding events without them having any meaning. Proper event tracing including consistency checks will also be done in a different test.

Note that this stupidly just adds new move events to the database. This is not what we do in the actual tracing, where consecutive move events are compacted into a single one. That too will be tested in different test methods. Here we just test the adding of events and the replacement of the identifier once a particle has moved too much.

Parameters

nsweeps	How many mesh sweeps to simulate.
nEventsToKeep	How many events per particle the database should keep. If < nsweeps, then events from the database will be purged.

testAddingSweepsToDatabase()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testAddingSweepsToDatabase ( )

private

Make sure that adding mesh sweeps to the database works.

Definition at line 263 of file TestHelpers.cpp.

References assertion3, assertion4, logTraceIn, and logTraceOut.

testParticleLiftDrop()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testParticleLiftDrop ( )

private

Test a particle being assigned up and down the vertex hierarchy.

testParticleMoveEvents()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testParticleMoveEvents ( )

private

Test adding move events of particles.

Calls testAddingParticleMovingEvents() with different configurations.

testParticleWalk()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testParticleWalk ( )

private

Test a particle walking through the box using lift-drop vertex assignments.

Definition at line 1105 of file TestHelpers.cpp.

References assertion, toolbox::particles::assignmentchecks::tests::internal::dropParticle(), dx, toolbox::particles::assignmentchecks::tests::internal::findVertexX(), toolbox::particles::assignmentchecks::tests::internal::liftParticle(), logDebug, logTraceIn, and logTraceOut.

Here is the call graph for this function:

testParticleWalkSameTreeLevel()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testParticleWalkSameTreeLevel ( )

private

Test a particle walking from vertex to vertex on the same depth of the tree, i.e.

assignments from vertex to vertex without lifts and drops.

Definition at line 736 of file TestHelpers.cpp.

References assertion2, assertion3, dx, toolbox::particles::assignmentchecks::tests::internal::findVertexInd(), toolbox::particles::assignmentchecks::tests::internal::findVertexX(), logDebug, logTraceIn, and logTraceOut.

Here is the call graph for this function:

testPeriodicBoundaryConditions()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testPeriodicBoundaryConditions ( )

private

Particles are identified in the events database using their unique ID.

However, if we have periodic boundary conditions, we may find that particles with the same ID exist several times on the same tree, on either side of the boundary, provided the tree spans both edges of the domain. So check that we indeed find the correct ancestors.

Here is the call graph for this function:

testPeriodicBoundaryConditionsCorner()

void toolbox::particles::assignmentchecks::tests::TestHelpers::testPeriodicBoundaryConditionsCorner ( )

private

Test the periodic boundary conditions of a particle in a corner, being replicated to any other corner of the box.

The assignment checks struggled with PBCs in the past, and they also had several bugs in it. So this test should prevent them from reoccurring. We assume that particles never cross the boundary.
