What steps can be taken to ensure a protractor test fails when a function does not succeed

For debugging my protractor test cases, I have developed helper methods. One of the key functions is waiting for an element to be clickable. To ensure that Protractor has enough time to find and enable the element, I am implementing a loop. However, in case the element is not located due to a typo or other issues in the script, I want the test run to immediately STOP and mark it as a FAILURE.

 async WaitToBeClickable(element){
       try{
           for(var i = 0; i <= 3000; i++){
               var wait = await browser.wait(this.EC.elementToBeClickable(element), i);
               if(wait == true){
                   break;
               }else{
                   //this is where I want to fail
               }
           }
       }catch(err){
           //this is where I want to fail
           await console.log(`WAIT TO BE CLICKABLE FAILED:\n${element.parentElementArrayFinder.locator_.value}\n\nError:\n${err}\n`);
       }
   };

This feature aids greatly in debugging my scripts while working on VSC. However, I am struggling to figure out how to make the test FAIL and close the browser upon the first failure. The options like protractor-fail-fast and protractor-bail-fast seem to cater to Jasmine test cases rather than individual functions. Any assistance would be highly appreciated as Protractor is making me a bit frustrated at the moment!

//function

const validateData = () => {
     return new Promise((resolve) => {
           if(true){
               // Passed scenario
               return resolve(true)
           }
           else{
               // Failed scenario
               return reject(false)
           }
  })
}


//Test file

it('example test', async () => {
    let result = await validateData();
    expect(result).toEqual(true);
})

The test outcome is based on the resolved value

If your code encounters an error, you can utilize the done function provided by Jasmine.

For example:

it('should perform a specific action', async done => {

    try {
        await performAction();
    } catch (e) {
        done.fail(e); // mark the test as failed
    }

    done(); // mark the test as completed
}, 1 * 60 * 1000);

async function performAction() {
    throw Error('the action failed');
}

async function performAction() {
    throw Error('the action failed');
}

Have you considered simply rethrowing the error in the catch block? This should trigger a test failure.

Feedback:

You don't need to await a console.log since it's a synchronous operation. Additionally, browser.wait will throw exceptions if the element isn't found within the specified timeout. It seems like your for loop may not be necessary here.

This function waits 3000ms for the element to become clickable. If the element doesn't become clickable within that time frame, an exception is thrown and caught in the catch block. The error message is logged before rethrowing the error, ultimately causing your test to fail (unless the error is handled elsewhere).

async WaitToBeClickable(element){
  try {
    await browser.wait(this.EC.elementToBeClickable(element), 3000);

  } catch (err) {
    console.log(`WAIT TO BE CLICKABLE FAILED:\n${element.parentElementArrayFinder.locator_.value}\n\nError:\n${err}\n`);
    throw new Error(err);
  }
};
