ExpectIt - is yet another pure Java 1.6+ implementation of the Expect tool. It is designed to be simple, easy to use and extensible. Written from scratch. Here are the features:

• Fluent-style API
• No third-party dependencies
• NIO based implementation using pipes and non-blocking API
• Extensible matcher framework
• Support regular expressions and group operations
• Support multiple input streams
• Support 'interact' loop
• Extensible filter framework to modify the input, for example, to remove non-printable ANSI terminal characters
• Custom Expect Ant Task
• Apache License

Example code:

// the stream from where you read your input data
InputStream inputStream = ...;
// the stream to where you send commands
OutputStream outputStream = ...;
Expect expect = new ExpectBuilder()
    .withInputs(inputStream)
    .withOutput(outputStream)
    .build();
expect.sendLine("command").expect(contains("string"));
Result result = expect.expect(regexp("(.*)--?--(.*)"));
// accessing the matching group
String group = result.group(2);
