= Testing with CSRF

Spring Security also provides support for CSRF testing with `WebTestClient`.
For example:

====
.Java
[source,java,role="primary"]
----
this.rest
	// provide a valid CSRF token
	.mutateWith(csrf())
	.post()
	.uri("/login")
	...
----

.Kotlin
[source,kotlin,role="secondary"]
----
this.rest
    // provide a valid CSRF token
    .mutateWith(csrf())
    .post()
    .uri("/login")
    ...
