Assert‐VerifiableMocks

Checks if any Verifiable Mock has not been invoked. If so, this will throw an exception.

Description

This can be used in tandem with the -Verifiable switch of the Mock function. Mock can be used to mock the behavior of an existing command and optionally take a -Verifiable switch. When Assert-VerifiableMocks is called, it checks to see if any Mock marked Verifiable has not been invoked. If any mocks have been found that specified -Verifiable and have not been invoked, an exception will be thrown.

Example 1

Mock Set-Content {} -Verifiable -ParameterFilter {$Path -eq "some_path" -and $Value -eq "Expected Value"}

{ ...some code that never calls Set-Content some_path -Value "Expected Value"... }

Assert-VerifiableMocks

This will throw an exception and cause the test to fail.

Example 2

Mock Set-Content {} -Verifiable -ParameterFilter {$Path -eq "some_path" -and $Value -eq "Expected Value"}

Set-Content some_path -Value "Expected Value"

Assert-VerifiableMocks

This will not throw an exception because the mock was invoked.
