I am building an automation framework in JavaScript for WebdriverIO.

The "out-of-the-box" error messages aren't too helpful and I would like to add the class name and method name as part of a prefix to the error message which is thrown when the method/function fails.

I have managed to call the class name with ClassName.name

However, I have not found a solution to reference the method name without using some hardcoded value.

Below is a summary of the changes I would like to make.

Before:

setElementValue(element, value){
    try{
        this.waitForElementAndScroll(element);
        $(element).setValue(value);
    }
    catch(error){
        throw `${BasePage.name}.setElementValue: ${error.message}`;
    }
}

After:

setElementValue(element, value){
    try{
        this.waitForElementAndScroll(element);
        $(element).setValue(value);
    }
    catch(error){
        throw `${BasePage.name}.${setElementValue.name}: ${error.message}`;
    }
}

Where ${setElementValue.name} is the method of referencing the name of the method/function.

Many thanks in advance!

I have tried the following with no success:

method.name //ReferenceError: method is not defined

(method).name //ReferenceError: method is not defined

Function.name //Returns "Function"

Function.value //Returns "undefined"

constructor.name //Returns "Object"

setElementValue.name //ReferenceError: setElementValue is not defined
