thrift-mock
A lightweight java unit test library for mocking thrift service
Features
- Init thrift mock server without any pre-define thrift idl, only a port is needed
- Dynamic binding thrift interface to its response
- Configurable response delays
- Support binding different interfaces from different thrift service to one server
- Embedded with junit4
- Support both blocking and non-blocking call
Getting Started
1. import maven dependency
working with junit
<dependency>
<groupId>com.didiglobal.thriftmock</groupId>
<artifactId>thrift-mock-server4junit</artifactId>
<version>1.0.2</version>
</dependency>
working without junit
<dependency>
<groupId>com.didiglobal.thriftmock</groupId>
<artifactId>thrift-mock-server</artifactId>
<version>1.0.2</version>
</dependency>
thrift test source
<dependency>
<groupId>com.didiglobal.thriftmock</groupId>
<artifactId>thrift-mock-server</artifactId>
<version>1.0.2</version>
</dependency>
2. start server
//working without junit, blocking server
ThriftMockServer server = new ThriftMockServer(9999);
Thread t = new Thread(server::start);
t.start();
//working without junit, starting a non-blocking server
AsyncThriftMockServer server = new AsyncThriftMockServer(9999);
Thread t = new Thread(server::start);
t.start();
//working with junit
//blocking server
@Rule
public ThriftMockServer server = new ThriftMockServer(9999);
//non-blocking server
@Rule
public AsyncThriftMockServer server = new AsyncThriftMockServer(9999);
3. bind interface with expect response
If you have a thrift file like this:
namespace java com.xiaoju.ddpay.thriftmock.server
struct Request{
1:optional string msg,
}
struct Response{
1:required i32 code,
2:required string responseMsg,
}
service HelloService {
Response sayHello(1:required Request request);
}
service ByeService {
Response sayBye(1:required Request request);
}
3.1 bind interface to fixed response
//define expect response
Response expectHelloResponse = new Response(200, "hello");
//bind response
server.setExpectReturn("sayHello", expectHelloResponse);
//bind response with specific delay(ms)
server.setExpectReturn("sayHello", expectHelloResponse, 100);
3.2 bind interface to dynamic response
//bind interface to dynamic response
TBase emptyArgs = new HelloService.sayHello_args();
Function<TBase, TBase> returnLogic = (tBase) -> {
HelloService.sayHello_args sayHello_args = (HelloService.sayHello_args)tBase;
if (sayHello_args.getRequest().getMsg().contains("fail")) {
return new Response(500, "fail");
}
return new Response(200, "success");
};
server.setExpectReturn("sayHello", emptyArgs, returnLogic);
3.3 request server
//init a thrift client connect to mock server
TTransport transport = new TSocket("127.0.0.1", 9999);
transport.open();
TProtocol protocol = new TBinaryProtocol(transport);
HelloService.Iface client = new HelloService.Client(protocol);
//request interface sayHello
Response msg = client.sayHello(request);
//get the expect response
Assert.assertEquals(msg.getCode(), 200);
Assert.assertEquals(msg.getMsg(), "hello");
Todo
- make it work like wiremock to test thrift service.
