EmptyConstraint - jnm2/nunit-docs-wiki GitHub Wiki

EmptyConstraint tests that an object is an empty string, directory or collection.

EmptyConstraint()

Is.Empty

Assert.That(aString, Is.Empty);
Assert.That(dirInfo, Is.Empty);
Assert.That(collection, Is.Empty);

• EmptyConstraint creates and uses either an EmptyStringConstraint, EmptyDirectoryConstraint or EmptyCollectionConstraint depending on the argument tested.
• A DirectoryInfo argument is required in order to test for an empty directory. To test whether a string represents a directory path, you must first construct a DirectoryInfo.
