perform() is not called after browser.actions()

Lately, I've noticed a peculiar line in one of our tests:

browser.actions().sendKeys(protractor.Key.RETURN);

Although the intention behind it is clear, it actually doesn't do anything because perform() was not called. Surprisingly, the test still passed, revealing a flaw in the logic and expectations of the test.

How can I catch these issues early on and prevent such violations of protractor/WebDriverJS usage from being committed to the repository?

Answer №1

If you're looking to improve your code quality, consider using static code analysis. There is a helpful linting tool called ESLint that offers various plugins to enhance your coding standards. For instance, there is now an available eslint-plugin-protractor plugin, which can detect protractor-specific issues like the misuse of browser.actions() without calling perform().

When running ESLint with this particular case, you might see an output similar to this:

/Users/user/job/app/specs/test.spec.js
36:13  error    No perform() called on browser.actions()        protractor/missing-perform

Answer №2

To achieve this, one possible method is through the implementation of a customizable editor plugin or integration of a specific linter rule.

While it is important to execute the test script in real-time for accurate evaluation, it is equally crucial to confirm that every test action is accompanied by a corresponding assertion or validation process.

The inclusion of Key.RETURN should trigger an event within the DOM, prompting actions such as page updates or data modifications that can be monitored and interpreted effectively, providing more meaningful insights compared to relying solely on static rules for analysis.
