An unexpected identifier error message "ERROR: Unexpected identifier firefox" occurred in Selenium Webdriver.io

While developing tests using Webdriver.io, a JavaScript API for Selenium WebDriver, everything was running smoothly until I encountered an error while trying to run the $ wdio wdio.conf.js command. The error message displayed as follows:

>ERROR: Unexpected identifier
firefox
Syntax    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:374:25)
    at Object.Module._extensions..js (module.js:417:10)
    at Module.load (module.js:344:32)
    at Function.Module._load (module.js:301:12)
    at Module.require (module.js:354:17)
    at require (internal/module.js:12:17)
    at Object.<anonymous> (/home/joe/Desktop/Webtesting/test/test.js:10:17)
    at Module._compile (module.js:410:26)
    at Object.Module._extensions..js (module.js:417:10)

The issue doesn't seem to lie within my code as even after reverting back to a previous commit, the same error persisted. It appears to be related to the wdio.conf.js file, particularly in this line. Surprisingly, changing the browser name to 'chrome' did not resolve the error:

   capabilities: [{
        maxInstances: 5,
        browserName: 'firefox'
    }],

Answer №1

After much investigation, I have identified the issue at hand. It turns out that the root cause was a simple syntax error within my code. The error message led me astray initially, as it referenced 'firefox', but in reality, this was just coincidental due to browser logging. The real culprit was a mistake in my code structure. So, remember to thoroughly inspect your own code for any syntax errors before jumping to conclusions about webdriver.io.
