How to Execute WebUI Feature File Across Multiple Browsers: Parallel Runner or Distributed Testing?

Execute WebUI Feature File Against Multiple Browsers Using Parallel Runner or Distributed Testing

Question:

How can the WebUI feature file be executed against multiple browsers (Zalenium) using the parallel runner or distributed testing?

Answer:

Using Scenario Outline and Parallel Runner:

Karate enables parallel execution of each row in an Examples table using a Scenario Outline. However, the driver configuration must be moved into the Feature.

Sample Project:

For reference, check out this sample project: https://github.com/intuit/karate/tree/master/examples/ui-test

Here's an example of a Scenario Outline:

Scenario Outline: <type>
  * def webUrlBase = karate.properties['web.url.base']
  * configure driver = { type: '#(type)', showDriverLog: true }

  * driver webUrlBase + '/page-01'
  * match text('#placeholder') == 'Before'
  * click('{}Click Me')
  * match text('#placeholder') == 'After'

Examples:
  | type         |
  | chrome       |
  | geckodriver  |

Alternative Pattern:

Another approach involves calling a normal Scenario from a separate Scenario Outline in a unique feature, as shown below:

Scenario Outline: <config>
  * configure driver = config
  * call read('main.feature')

Examples:
  | config!                  |
  | { type: 'chromedriver' } | 
  | { type: 'geckodriver' }  | 
  | { type: 'safaridriver' } |

Other Ideas:

• Reuse the same browser instance for all tests, as demonstrated in the Karate CI regression test: https://stackoverflow.com/a/66762430/143475
