Simulating remote HTTP servers for functional testing

This is a test fixture, which provides a very basic servlet that registers expected requests and logs access counts for each requested method/pathParts combination. If no expectation is registered for a particular method/pathParts, 404 is returned.

Usage is pretty simple:

For junit 4 Rule based

@Rule
public ExpectationServerRule serverRule = new ExpectationServerRule( "repos" );

@Test
public void run()
    throws Exception
{
    final ExpectationServer server = serverRule.getServer();
    final String pathParts = "/repos/pathParts/to/something.txt";
    final String content = "this is the content";
    final String url = server.formatUrl( pathParts );
    server.expect( url, 200, content );
    // Do any assertions....
    .......
}

For junit 5 Extension Based:

@ExtendWith(ExpectationServerExtension.class)
public class ExpectaionTest{

    @Expected("repos")
    public ExpectationServer server;
 
    @Test
    public void run()
        throws Exception
    {
        final String pathParts = "/repos/pathParts/to/something.txt";
        final String content = "this is the content";
        final String url = server.formatUrl( pathParts );
        server.expect( url, 200, content );
        // Do any assertions....
        .......
    }
}

or:

public class ExpectaionTest{

    @RegisterExtension
    public ExpectationServerExtension extension = new ExpectationServerExtension("repos");
 
    @Test
    public void run()
        throws Exception
    {
        final ExpectationServer server = extension.getServer();
        final String pathParts = "/repos/pathParts/to/something.txt";
        final String content = "this is the content";
        final String url = server.formatUrl( pathParts );
        server.expect( url, 200, content );
        // Do any assertions....
        .......
    }
}

Quarkus Based Test

There are some limitations to let junit5 @ExtendWith work together with @QuarkusTest, see quarkusio/quarkus#24911 (comment)
So to make it work, here brings the new annotation to make it work.

@QuarkusTest
public class ExpectaionTest{

    @InjectExpected("repos")
    ExpectationServer server;
 
    @Test
    public void run()
        throws Exception
    {
        final String pathParts = "/repos/pathParts/to/something.txt";
        final String content = "this is the content";
        final String url = server.formatUrl( pathParts );
        server.expect( url, 200, content );
        // Do any assertions....
        .......
    }
}
