Let's look at how we can make that work.

## pytest.mark.anyio

If we want to call asynchronous functions in our tests, our test functions have to be asynchronous. AnyIO provides a neat plugin for this, that allows us to specify that some test functions are to be called asynchronously.

    assertThat(stringPrep("\u2ffb")).isNull()
  }

  @Test fun prohibitionChangeDisplayPropertiesOrDeprecated() {
    assertThat(stringPrep("\u0340")).isNull() // COMBINING GRAVE TONE MARK
    assertThat(stringPrep("\u200e")).isNull() // LEFT-TO-RIGHT MARK
    assertThat(stringPrep("\u206e")).isNull() // NATIONAL DIGIT SHAPES
    assertThat(stringPrep("\u206f")).isNull() // NOMINAL DIGIT SHAPES
