Test order with espresso

Is there a way to set test running order in android? I use Espresso framework and need to test a lot of activities and transitions between them. I want to write different test for those activities, but I need a specific order for running those tests.

As @spinster said above, you should write your tests in a way where order doesn't matter.

I believe Junit 3 will run tests in alphabetical order of the fully qualified class name, so in theory you could control the order by naming them ( package name, class name, method name ) alphabetically in the order you would like them executed, but I would not recommend that.

Create UI tests with Espresso Test Recorder, When you run the test, the Espresso test will try executing these actions in the same order Duration: 3:28 Posted: Sep 19, 2016 In order to make sure we are on the right track with each new release, the test runner collects analytics. More specifically, it uploads a hash of the package name of the application under test for each invocation. This allows us to measure both the count of unique packages using Espresso as well as the volume of usage.

From Junit 4.11 comes with @FixMethodOrder annotation. Instead of using custom solutions just upgrade your junit version and annotate test class with FixMethodOrder(MethodSorters.NAME_ASCENDING). Check the release notes for the details.

Here is a sample:

import org.junit.runners.MethodSorters;

import org.junit.FixMethodOrder;
import org.junit.Test;

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class SampleTest {

   @Test
   public void A_firstTest() {
      System.out.println("first");
   }

   @Test
   public void B_secondTest() {
      System.out.println("second");
   }
}

  • As good testing practice, your tests really should not have an order. You may want to take a step back and analyze your situation.
  • @spinster - I agree the unit tests should run in any order however the testing Frameworks now have been extended for Integration/Component as well as Functional tests which most often requires ordering. As an example you would need a database tables to exist before you can component tests CRUD operations. Perhaps we could argue then those frameworks such as Spring, Android Espresso etc should provide such ordering. However that would require altering the core libraries, hence it would be a nice feature to have suite level ordering with in Junit.
  • wow...that sounds crazy to me...the test suite could take forever if each test method required its own setup...especially if the setup functionality has already been tested by a previously ran test method..with that methodology, you would be retesting scenarios over and over again just to get to the required states for each given test method...if specifying a test order is a bad idea...forcing alphabetical is an even worse one.
  • Yes, it is a bit "crazy" and I would not recommend it, but it was an answer to the question posed.
  • I don't agree, what if you are testing api call that store api token in memory (with singleton) and other test access that token. Do you still think that order does not matter?
  • What if you want to run the test in order (with the class name)?
  • you can put some authorization\deauthorization functionality out from the test into specific methods. Then from LoginTest you just call authorization method, from LogoutTest - authorization and then deauthorization. Other tests will then extend some BaseTest which will have authorization in setUp method, and, if needed, deauthorization in tearDown
