### Motivation

This library makes it easy to test that your app Does The Right Thing when it
makes HTTP and HTTPS calls. It lets you specify which responses to return and
then verify that requests were made as expected.

Because it exercises your full HTTP stack, you can be confident that you're
testing everything. You can even copy & paste HTTP responses from your real web
server to create representative test cases. Or test that your code survives in

    .build();
```

With a server that holds a certificate and a client that trusts it we have enough for an HTTPS
handshake. The best part of this example is that we don't need to make our test code insecure with a
a fake `HostnameVerifier` or `X509TrustManager`.

Certificate Authorities
-----------------------

`StringprepTablesReader` into a model that can be used at runtime.

This format is chosen to make it easy to validate that these tables are consistent with the RFC.

```
cd okhttp/src/test/resources/okhttp3/internal/idn/
ls rfc3454.*.txt | xargs -n 1 -I {} bash -c "echo {} ; cat {}" > okhttp_tables.txt
curl https://www.rfc-editor.org/rfc/rfc3454.txt > rfc3454.txt
diff rfc3454.txt okhttp_tables.txt | less

To use, first add this library as a test dependency:

```
testRuntimeOnly("com.squareup.okhttp3:mockwebserver3-junit5:4.12.0")
```

Then in tests annotated `@org.junit.jupiter.api.Test`, you may add a [MockWebServer] as a test
method parameter. It will be shut down automatically after the test runs.

```
class MyTest {
  @Test
  void test(MockWebServer server) {
    ...
  }
}
```

MockWebServer for JUnit 4
=========================

This module integrates mockwebserver3.MockWebServer with JUnit 4.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit4:4.12.0")
```

Then in tests annotated `@org.junit.Test`, you may declare a field with the `@Rule` annotation:

```
@Rule public final MockWebServerRule serverRule = new MockWebServerRule();
```
