Contributions are welcome in Pester-repo.

SYNOPSIS​

Ensures that the input is a string, and that the input is not $null, empty, or whitespace only string.

SYNTAX​

Should-NotBeWhiteSpaceString [[-Actual] <Object>] [-Because <string>]

DESCRIPTION​

This assertion requires a string that contains at least one non-whitespace character. It fails for $null, ""`, whitespace-only strings, and non-string values.

EXAMPLES​

EXAMPLE 1​

$actual = "hello"
$actual | Should-NotBeWhiteSpaceString

This test will pass.

EXAMPLE 2​

$actual = "  "
$actual | Should-NotBeWhiteSpaceString

This test will fail, the input is a whitespace only string.

EXAMPLE 3​

$null | Should-NotBeWhiteSpaceString
"" | Should-NotBeWhiteSpaceString
$() | Should-NotBeWhiteSpaceString
$false | Should-NotBeWhiteSpaceString
1 | Should-NotBeWhiteSpaceString

All the tests above will fail, the input is not a string.

OUTPUTS​

NOTES​

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.
