4) Use Cypress for Browser Testing

Context

WikibaseLexeme browser tests used to be written using WebdriverIO (wdio) / Selenium in sync mode. This is no longer supported since Node 16 and WebdriverIO 8. As a result, we have already had to stop running the browser tests in CI, and need to decide how to move forward with our browser tests.

Considered Actions

We identified the following options:

1. Rewrite the tests using async mode of WebdriverIO.
2. Rewrite the tests using Cypress and drop WebdriverIO.

See also EntitySchema ADR 0002, where we were faced with the same decision, for more details on each option.

(The theoretically possible option of not having any browser tests was not seriously considered.)

Decision

We will go with Cypress.

Consequences

We will set up Cypress testing, then rewrite the existing tests in Cypress and drop their WebdriverIO code.
