Preventing driver closure during test suites in Appium/Webdriverio: a step-by-step guide

Currently, I am in the process of testing a react native application with a specific test suite and test cases.

The test case files I am working with are:

  • login.ts
  • doActionAfterLogin_A.ts

Test Suite: [login.ts, doActionAfterLogin_A.ts]

Issue at Hand: While working on login.ts, I need to ensure that the desired capability appium:noReset is set to false in order to test the flow of a fresh installation. However, for doActionAfterLogin_A.ts, I require appium:noReset to be set to true to skip the fresh installation flow.

The dilemma arises when Appium closes the browser/driver between test cases in the suite and relaunches with the same desired capabilities, resulting in appium:noReset always being false. Is there a way to:

  1. Prevent the browser/driver from closing between test cases
  2. Modify the desired capabilities between test cases
  3. Re-evaluate the structure of my test cases

Additional Information: Utilizing Appium, Webdriverio, Mocha, and Typescript

Thank you for your assistance!

Answer №1

It seems that changing DesiredCapabilities mid-session with an AppiumDriver is not possible. However, in your case, I recommend separating your Appium setup from your .ts test scripts.

  • Develop a projectCapabilities.ts file to configure the AppiumDriver and the Capabilities
  • Implement a hook to define the Setup and TearDown processes
  • Organize a Mocha Test Suite with individual Test Cases for each .ts file
before(setup() {});
it('Test Case Name', testcase1Login(){});
it('Test Case Name', testcase2DoAfterLogin(){});
after(teardown() {});

By utilizing system/environment variables, I am able to set the driver capability values. In the event that there is no corresponding system/env variable, I have default values as a backup. However, if I need to modify a capability for a specific test, I always ensure to set the system/env variable beforehand.

The procedure for each test is as follows:

  1. Set system/env variable "noReset" to true or false based on the requirements of your test
  2. Instantiate the driver with the capability "noReset" to reflect the value of the "noReset" system/env variable
  3. Execute the test logic
