Should-BeSame

This page was generated

Contributions are welcome in Pester-repo.

SYNOPSIS​

Compares the expected value to actual value, to see if they are the same instance.

SYNTAX​

Should-BeSame [-Expected] <Object> [[-Actual] <Object>] [-Because <string>]

DESCRIPTION​

This assertion checks reference equality rather than value equality. Use it with reference types when you need to verify that both variables point to the same instance.

EXAMPLES​

EXAMPLE 1​

$a = New-Object Object
$a | Should-BeSame $a

This assertion will pass, because the actual value is the same instance as the expected value.

EXAMPLE 2​

$a = New-Object Object
$b = New-Object Object
$a | Should-BeSame $b

This assertion will fail, because the actual value is not the same instance as the expected value.

OUTPUTS​

NOTES​

The Should-BeSame assertion is the opposite of the Should-NotBeSame assertion.

Use the -ErrorAction parameter to control soft-assertion behavior for this assertion. -ErrorAction Continue records the failure and lets the rest of the test run (a soft assertion), while -ErrorAction Stop fails the test immediately, for example to guard a precondition before continuing.

When -ErrorAction is not specified, the behavior comes from Should.ErrorAction in the configuration, which defaults to Stop. See https://pester.dev/docs/assertions/soft-assertions for more about soft assertions.
