Espresso overview
This SDK allows you to work with Applitools Eyes using Espresso.
Getting started
To get started with this SDK, you need to set the following:
- Applitools API key
- Eyes server URL – Required only if the Eyes server is not deployed on the Eyes public server.
Entering the Applitools API key
To authenticate via the Applitools server and run tests, you need to set the environment variable APPLITOOLS_API_KEY
to the API key provided from Applitools Eyes. For details how to retrieve your API key, see the Applitools documentation.
Entering the API Key on Linux or a Mac
export APPLITOOLS_API_KEY=<API_key>
Entering the API Key on Windows
set APPLITOOLS_API_KEY=<API_key>
Eyes server URL
If the Eyes server is not deployed in https://eyes.applitools.com
, you need to set the Server URL in the environment variable APPLITOOLS_SERVER_URL
before running tests.
The server URL of your Applitools Eyes dashboard is in the format https://<MY_COMPANY>.applitools.com
Entering the server URL on Linux or a Mac
export APPLITOOLS_SERVER_URL=<YOUR_SERVER_URL>
Entering the server URL on Windows
set APPLITOOLS_SERVER_URL=<YOUR_SERVER_URL>
Recommended practice for using the SDK
A test in Applitools Eyes always starts with a eyes.open
call and ends with eyes.close
. The steps in the test are calls to eyes.check
between eyes.open
and eyes.close
calls.
A test is structured as following:
eyes.open
[step 1]
[step 2]
...
eyes.close
Runner
This SDK uses the following Runner classes:
- ClassicRunner – Used when running multiple Eyes sessions.
- VisualGridRunner – Used to manage sessions when working with the Native Mobile Grid.
ClassicRunner class
An object of this class is used to manage multiple Eyes sessions when working without the Native Mobile Grid
Constructor
To define the class:
EyesRunner runner = new ClassicRunner();
GetAllTestResults
This command returns an object with the Eyes test results from a given test or test file. This command should be called after all Eyes tests have been completed.
TestResultsSummary allTestResults = runner.getAllTestResults();
System.out.println(allTestResults);
dontCloseBatches
If true
, the batch is not closed when GetAllTestResults
is called.
runner.setDontCloseBatches(true)
Constructor
To define the class:
EyesRunner runner = new VisualGridRunner(new RunnerOptions().testConcurrency(5));
GetAllTestResults
This command returns an object with the results from a test or test file. This command should be called after all Eyes tests have been completed.
Example
TestResultsSummary allTestResults = runner.getAllTestResults();
Log.i(TAG, allTestResults);
Eyes class
Eyes Class enables visual testing with Applitools Eyes.
Constructor
To define the class:
Eyes eyes = new Eyes(runner);
eyes.open
This method creates an Eyes test. This will start a session with the Applitools server.
eyes.open("app name", "test name");
Where:
-
"app name" – The application name, this may be any string. You can set the application name for all tests using
Configuration.setAppName
, in which case you do not need to set the app name, use useeyes.open("test name");
. -
"test name" – The name of the test. This name must be unique within the scope of the application name. It may be any string.
eyes.check
This command generates a screenshot of the application and adds it to the Eyes test.
eyes.check(Target.window());
For details of eyes.check
arguments, see CheckSettings class.
eyes.close
This command closes the Eyes test and checks that all screenshots are valid. It is important to call this command at the end of each test, symmetrically to eyes.open
.
eyes.close
receives no arguments.
eyes.closeAsync();
Sample test
To help you get started, the following samples check the initial screen in your application:
Classic (when Native Mobile Grid is not Used)
Other Significant classes
When working with this SDK, you should be familiar with the following classes:
- Configuration class – Used to create a configuration object that is used to configure an Eyes object by passing it to the
Eyes.setConfiguration
method.
