Conversions

When executing tests, LCT generates Playwright code for the test runner. As test development progresses, the generated files will change naturally. LCT stores the different versions of these code files as Conversions.

Select a conversion for execution​

In the Schedule Test dialog, you can choose either a specific version number or Latest possible.

Each time a Worksheet is executed with the Latest possible option LCT performs the following steps:

  1. Call the test converter to translate the test cases and steps into Playwright code.
  2. Check if a conversion already exists.
    • If yes: Proceed with the next step.
    • If no: Set this conversion as version 1. Skip step 3.
  3. Retrieve the latest conversion and compare with converter output.
    • If equal: Proceed with the next step.
    • If not equal: Save the converted output as a new conversion.
    • Note: LCT does not perform comparison directly. Instead, it uses the SHA256 checksums of both lct.spec.js files to detect changes.
  4. Call the test runner with the converted code to execute the Worksheet.
note

In Test Suites, the conversion cannot be set. Instead, it always will use the option Latest possible.

View conversion output​

To view the contents of the converted file:

  1. Open the Queue page.
  2. Select an entry where the desired conversion was used.
  3. In the corresponding Actions menu, select Version Details.

A dialog will open which shows a list of the test cases on the left and the Playwright code on the right. More specifically, it displays the content of the lct.spec.js file as generated by the converter.

note

Variable replacement is part of the execution pipeline. Therefore, values will be shown as entered in the step editor.

To view and download all files in their final state, use the Test Files option in the Actions menu.
