1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

### Java
```java
public void test() throws Exception {
  // Create a MockWebServer. These are lean enough that you can create a new
  // instance for every unit test.
  MockWebServer server = new MockWebServer();

  // Schedule some responses.
  server.enqueue(new MockResponse.Builder()
      .body("hello, world!")

        // create input source
        final InputSource is = new InputSource(new ByteArrayInputStream(accessResultData.getData()));
        if (StringUtil.isNotBlank(accessResultData.getEncoding())) {
            is.setEncoding(accessResultData.getEncoding());
        }

        // create handler
        final DocHandler handler = new DocHandler();

        // Arrange
        stubAcquireReturnsSelf();
        List<FileEntry[]> pages = List.of(new FileEntry[][] { new FileEntry[] {} });

        // Create iterator where open() returns null by giving null initial
        TestIterator it = TestIterator.create(tree, parent, "*", null, 0, null, pages);

        // Assert
        assertFalse(it.hasNext(), "No next when opened with null initial");
