Tests for operators.

class armi.operators.tests.test_operators.InterfaceA(r, cs)

Bases: Interface

Construct an interface.

The r and cs arguments are required, but may be None, where appropriate for the specific Interface implementation.

Parameters:

• r (Reactor) – A reactor to attach to

• cs (Settings) – Settings object to use

Raises:

RuntimeError – Interfaces derived from Interface must define their name

function = 'A'

The function performed by an Interface. This is not required be be defined by implementations of Interface, but is used to form categories of interfaces.

name: Optional[str] = 'First'

The name of the interface. This is undefined for the base class, and must be overridden by any concrete class that extends this one.

class armi.operators.tests.test_operators.InterfaceB(r, cs)

Bases: InterfaceA

Dummy Interface that extends A.

Construct an interface.

The r and cs arguments are required, but may be None, where appropriate for the specific Interface implementation.

Parameters:

• r (Reactor) – A reactor to attach to

• cs (Settings) – Settings object to use

Raises:

RuntimeError – Interfaces derived from Interface must define their name

function = 'A'

The function performed by an Interface. This is not required be be defined by implementations of Interface, but is used to form categories of interfaces.

name: Optional[str] = 'Second'

The name of the interface. This is undefined for the base class, and must be overridden by any concrete class that extends this one.

class armi.operators.tests.test_operators.InterfaceC(r, cs)

Bases: Interface

Construct an interface.

The r and cs arguments are required, but may be None, where appropriate for the specific Interface implementation.

Parameters:

• r (Reactor) – A reactor to attach to

• cs (Settings) – Settings object to use

Raises:

RuntimeError – Interfaces derived from Interface must define their name

function = 'A'

The function performed by an Interface. This is not required be be defined by implementations of Interface, but is used to form categories of interfaces.

name: Optional[str] = 'Third'

The name of the interface. This is undefined for the base class, and must be overridden by any concrete class that extends this one.

class armi.operators.tests.test_operators.OperatorTests(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_operatorData()

Test that the operator has input data, a reactor model.

test_orderedInterfaces(interactAll)

Test the default interfaces are in an ordered list, looped over at each time step.

test_addInterfaceSubclassCollision()

test_interfaceIsActive()

test_getActiveInterfaces()

Ensure that the right interfaces are returned for a given interaction state.

test_loadStateError()

The loadTestReactor() test tool does not have any history in the DB to load from.

test_setStateToDefault()

test_snapshotRequest(fakeDirList, fakeCopy)

class armi.operators.tests.test_operators.TestCreateOperator(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_createOperator()

Test that an operator can be created from settings.

class armi.operators.tests.test_operators.TestTightCoupling(methodName='runTest')

Bases: TestCase

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.

test_getStepLengths()

Test the step lengths are correctly calculated, based on settings.

test_couplingIsActive()

Ensure that cs[CONF_TIGHT_COUPLING] controls couplingIsActive.

test_performTightCoupling_Inactive()

Ensures no action by _performTightCoupling if cs[CONF_TIGHT_COUPLING] = false.

test_performTightCoupling_skip()

Ensure that cycles within cs[CONF_CYCLES_SKIP_TIGHT_COUPLING_INTERACTION] are skipped.

test_performTightCoupling_notConverged()

Ensure that the appropriate runLog.warning is addressed in tight coupling reaches max num of iters.

test_performTightCoupling_WriteDB()

Ensure a tight coupling iteration accours and that a DB WILL be written if requested.

test_performTightCoupling_NoWriteDB()

Ensure a tight coupling iteration accours and that a DB WILL NOT be written if requested.

dbWriteForCoupling(writeDB: bool)

test_computeTightCouplingConvergence()

Ensure that tight coupling convergence can be computed and checked.

Notes

• Assertion #1: ensure that the convergence of Keff, eps, is greater than 1e-5 (the prescribed convergence criteria)

• Assertion #2: ensure that eps is (prevIterKeff - currIterKeff)

class armi.operators.tests.test_operators.CyclesSettingsTests(methodName='runTest')

Bases: TestCase

Check that we can correctly access the various cycle settings from the operator.

Create an instance of the class that will use the named test method when executed. Raises a ValueError if the instance does not have a method with the specified name.
