SYNOPSIS

Asserts that the actual value is not equal to the expected value.

SYNTAX

Should-NotBeString [[-Expected] <string>] [[-Actual] <Object>] [-Because <string>] [-CaseSensitive]
 [-IgnoreWhitespace]

DESCRIPTION

The Should-NotBeString assertion compares the actual value to the expected value using the -ne operator. The -ne operator is case-insensitive by default, but you can make it case-sensitive by using the -CaseSensitive switch.

EXAMPLES

EXAMPLE 1

"hello" | Should-NotBeString "HELLO"

This assertion will pass, because the actual value is not equal to the expected value.

EXAMPLE 2

"hello" | Should-NotBeString "hello" -CaseSensitive

This assertion will fail, because the actual value is equal to the expected value.

OUTPUTS

NOTES

The Should-NotBeString assertion is the opposite of the Should-BeString 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.
