Custom function in testcafe
So, i am trying to create a custom function that will allow me to check if a field contains a number or a text, but for further test i will need to check more complex stuff, like if the sum of some table equals something, etc.
I can't find examples of custom functions for example:
function isNumber(n) a < 0)
return true
return false
test('Test example', async t =>
await t
.expect(isNumber(Selector('#thisNum').innerText)).ok('This is a number' );
);javascript automated-tests e2e-testing testcafe

The assertion message will only be displayed when the assertion fails (refer to the message parameter). For example,
await t
.expect(failingValue).ok('failingValue is not a number');
Would display something like the following on a failed test:
1) AssertionError: failingValue is not a number: expected false to be truthy
Therefore, I'd never expected to see the "This is a number" message displayed.
As for the function, I've experienced a couple of instances where the promise wasn't resolved yet, so try awaiting the number selector:
await t
.expect(isNumber(await Selector('#thisNum').innerText)).ok('This is a number');
Hope this helps.
