Interacting with a non-stringified object displayed in the browser console using TestCafe

Upon receiving a page that logs an object to the console, I encountered an issue when trying to access this object using getBrowserConsoleMessages(). The object appeared as the String "[object Object]" in the console, making it impossible for me to parse and access its properties. Is there something crucial that I am overlooking?

<!DOCTYPE html>
<html>
<body>
    <script>console.log({message: 'Hello, world!'});</script>
</body>
</html>
fixture.page("http://127.0.0.1:5500/test.html")("Check page");

test("Console accessible", async t => {
    const { log } = await t.getBrowserConsoleMessages()
    console.log(JSON.parse(log[0]).message)
})

Answer №1

When using the 'console.log' function, data gathered from the client side is in string form and does not include serialization of objects in console messages. TestCafe currently has an issue with this: Improving object serialization for browser console messages.

As a temporary solution, you can try the following workarounds:

  1. Serialize object variables on the client-side using JSON.stringify, then parse them in your test using JSON.parse.
  2. Inject Client Scripts into your page and override the client-side console.log function to stringify the passed argument. For example, create a client script named 'overrideLogs.js' with the code:
var originalConsoleLog = console.log;
console.log = data => originalConsoleLog(JSON.stringify(data));

Run your tests in TestCafe with the specified client script:

testcafe chrome test.js --client-scripts overrideLogs.js

This will allow the output to display messages from objects logged on the page.
