Nearly 70 million people worldwide have downloaded our mobile app to date; 9 million in Q4 2013.
One of the 25 most downloaded free apps of all time
Nearly 50% of our global transactions completed on a mobile device in December 2013
The Problem
Test data from WebService(s)
Mock data?
• Easy with DI frameworks
• Hard with black box test frameworks• Do not reflect server changes
+
-
Use real data?
• Real world
• Hard to setup all test cases(manipulate db with scripts …)
• Automation mostly breaks because of networking
+
-
Do both
• Return mocked data if needed
• Use real world real data
• Modify data on the fly if needed
We need:
• Someone who can change
depending on what is needed?
A Solution
Odo-ed
Response Override
• Return fixed response content
• Return fixed response code
• Add delays
Response Override cont.
• Add/remove request headers
• Change content
• Change response code
Response Override cont.
• Do sequences of all those
• Supports Plugins for custom responses
i.e. makeDealSoldOut
Request Override
• Add/remove request headers
• Custom request – add/change parameters
• Change the target
i.e. send production request to staging/test
Odo Demo
Build a plugin
public class MyPlugins {
@ResponseOverride( httpCode=302, description="Return HTTP302") public static String http302(String source) throws Exception { return „<html><body>You are being redirected.</body></html>“; }
Done
Configuration
• No installation needed, simple war file
• Webinterface
• API
API
• JSON REST API
• Java Client available
public class OdoTest extends ActivityInstrumentationTestCase2<LoginActivity> { Client odoClient = new Client("33", false);
public void testOdo() throws Exception {LoginActivity activity = getActivity();
// genymotion != localhost odoClient.setHostName("192.168.56.1"); odoClient.addMethodToResponseOverride(
"Countries", "com.groupon.odo.internal.Common.http503");
odoClient.toggleResponseOverride("Countries", true); }}
What do you have to change in your app?
Proxy proxy = new Proxy(
Proxy.Type.HTTP,
new InetSocketAddress(
"192.168.56.1", 9090));
new URL("http://api...").openConnection(proxy);
HttpUrlConnection
OkHttp
Proxy proxy = new Proxy(
Proxy.Type.HTTP,
new InetSocketAddress(
"192.168.56.1", 9090));
OkHttpClient client = new OkHttpClient();
client.setProxy(proxy);
DefaultHttpClient httpclient =
new DefaultHttpClient();
httpclient.getParams().setParameter(
ConnRoutePNames.DEFAULT_PROXY,
new HttpHost("192.168.56.1", 9090));
Old school apache
Configuration
• Supports multiple users through client id’s
• This way you can share proxy
• Apps send them as http-header
Configuration
• Forwarding proxy mode
• Man in the middle mode
• SSL certificate download page
Behind odo
• Utilizes forwarding proxy, Spring, Spring Boot, Java servlets, embedded database
• Packaged as a .war file
• No setup required
Advantages
• Test Automation
• Avoid stub data maintenance
• Create dynamic test automation
• Manual Test
• UI allows easy configuration changes
• No coding knowledge required
• Development
• Remove dependencies on server changes for
client development
Odo + vs Charles
• Is free• Is open source• Is “programmable”• Is extendable via plugins• Has API• Perfect for test automation
