Google Apps Script supports Triggers, that pass Events to trigger functions. Unfortunately, the development environment will let you test functions with no parameter passing, so you cannot simulate an event that way. If you try, you get an error like:
ReferenceError: 'e' is not defined.
Or
TypeError: Cannot read property *...* from undefined
(where e is undefined)
One could treat the event like an optional parameter, and insert a default value into the trigger function using any of the techniques from Is there a better way to do optional function parameters in JavaScript?. But that introduces a risk that a lazy programmer (hands up if that's you!) will leave that code behind, with unintended side effects.
Surely there are better ways?
You can write a test function that passes a simulated event to your trigger function. Here's an example that tests an onEdit() trigger function. It passes an event object with all the information described for "Spreadsheet Edit Events" in Understanding Events.
To use it, set your breakpoint in your target onEdit function, select function test_onEdit and hit Debug.
/**
* Test function for onEdit. Passes an event object to simulate an edit to
* a cell in a spreadsheet.
*
* Check for updates: https://stackoverflow.com/a/16089067/1677912
*
* See https://developers.google.com/apps-script/guides/triggers/events#google_sheets_events
*/
function test_onEdit() {
onEdit({
user : Session.getActiveUser().getEmail(),
source : SpreadsheetApp.getActiveSpreadsheet(),
range : SpreadsheetApp.getActiveSpreadsheet().getActiveCell(),
value : SpreadsheetApp.getActiveSpreadsheet().getActiveCell().getValue(),
authMode : "LIMITED"
});
}
If you're curious, this was written to test the onEdit function for Google Spreadsheet conditional on three cells.
Here's a test function for Spreadsheet Form Submission events. It builds its simulated event by reading form submission data. This was originally written for Getting TypeError in onFormSubmit trigger?.
/**
* Test function for Spreadsheet Form Submit trigger functions.
* Loops through content of sheet, creating simulated Form Submit Events.
*
* Check for updates: https://stackoverflow.com/a/16089067/1677912
*
* See https://developers.google.com/apps-script/guides/triggers/events#google_sheets_events
*/
function test_onFormSubmit() {
var dataRange = SpreadsheetApp.getActiveSheet().getDataRange();
var data = dataRange.getValues();
var headers = data[0];
// Start at row 1, skipping headers in row 0
for (var row=1; row < data.length; row++) {
var e = {};
e.values = data[row].filter(Boolean); // filter: https://stackoverflow.com/a/19888749
e.range = dataRange.offset(row,0,1,data[0].length);
e.namedValues = {};
// Loop through headers to create namedValues object
// NOTE: all namedValues are arrays.
for (var col=0; col<headers.length; col++) {
e.namedValues[headers[col]] = [data[row][col]];
}
// Pass the simulated event to onFormSubmit
onFormSubmit(e);
}
}
Tips
When simulating events, take care to match the documented event objects as close as possible.
If you wish to validate the documentation, you can log the received event from your trigger function.
Logger.log( JSON.stringify( e , null, 2 ) );
In Spreadsheet form submission events:
all namedValues values are arrays.
Timestamps are Strings, and their format will be localized to the Form's locale. If read from a spreadsheet with default formatting*, they are Date objects. If your trigger function relies on the string format of the timestamp (which is a Bad Idea), take care to ensure you simulate the value appropriately.
If you've got columns in your spreadsheet that are not in your form, the technique in this script will simulate an "event" with those additional values included, which is not what you'll receive from a form submission.
As reported in Issue 4335, the values array skips over blank answers (in "new Forms" + "new Sheets"). The filter(Boolean) method is used to simulate this behavior.
*A cell formatted "plain text" will preserve the date as a string, and is not a Good Idea.
Update 2020-2021:
You don't need to use any kind of mocks events as suggested in the previous answers.
As said in the question, If you directly "run" the function in the script editor, Errors like
TypeError: Cannot read property ... from undefined
are thrown. These are not the real errors. This error is only because you ran the function without a event. If your function isn't behaving as expected, You need to figure out the actual error:
To test a trigger function,
Trigger the corresponding event manually: i.e., To test onEdit, edit a cell in sheet; To test onFormSubmit, submit a dummy form response; To test doGet, navigate your browser to the published webapp /exec url.
If there are any errors, it is logged to stackdriver. To view those logs,
In Script editor > Execution icon on the left bar(Legacy editor: View > Executions).
Alternatively, Click here > Click the project you're interested in > Click "Executions" icon on the left bar(the 4th one)
You'll find a list of executions in the executions page. Make sure to clear out any filters like "Ran as:Me" on the top left to show all executions. Click the execution you're interested in, it'll show the error that caused the trigger to fail in red.
Note: Sometimes, The logs are not visible due to bugs. This is true especially in case of webapp being run by anonymous users. In such cases, It is recommended to Switch Default Google cloud project to a standard Google cloud project and use View> Stackdriver logging directly. See here for more information.
For further debugging, You can use edit the code to add console.log(/*object you're interested in*/) after any line you're interested in to see details of that object. It is highly recommended that you stringify the object you're looking for: console.log(JSON.stringify(e)) as the log viewer has idiosyncrasies. After adding console.log(), repeat from Step 1. Repeat this cycle until you've narrowed down the problem.
Congrats! You've successfully figured out the problem and crossed the first obstacle.
2017 Update:
Debug the Event objects with Stackdriver Logging for Google Apps Script. From the menu bar in the script editor, goto:
View > Stackdriver Logging to view or stream the logs.
console.log() will write DEBUG level messages
Example onEdit():
function onEdit (e) {
var debug_e = {
authMode: e.authMode,
range: e.range.getA1Notation(),
source: e.source.getId(),
user: e.user,
value: e.value,
oldValue: e. oldValue
}
console.log({message: 'onEdit() Event Object', eventObject: debug_e});
}
Example onFormSubmit():
function onFormSubmit (e) {
var debug_e = {
authMode: e.authMode,
namedValues: e.namedValues,
range: e.range.getA1Notation(),
value: e.value
}
console.log({message: 'onFormSubmit() Event Object', eventObject: debug_e});
}
Example onChange():
function onChange (e) {
var debug_e = {
authMode: e.authMode,
changeType: changeType,
user: e.user
}
console.log({message: 'onChange() Event Object', eventObject: debug_e});
}
Then check the logs in the Stackdriver UI labeled as the message string to see the output
As an addition to the method mentioned above (Update 2020) in point 4.:

I'm using Parsley.js to validate part of a form like in this example. However, the validate() method always returns false, even when that piece of form should validate.
No error messages are displaying, and I want to see what it is that's failed validation.
I can't see a way to get Parsley to simply return all the errors found, so I can see them in the console. Have I missed something obvious?
You can use something like this:
window.Parsley.on('field:error', function() {
// This global callback will be called for any field that fails validation.
console.log('Validation failed for: ', this.$element);
});
from http://parsleyjs.org/doc/index.html#events
There are probably (hopefully) better ways to do this, but this kind of thing is what I ended up using to get some insight into what's being validated and what is/isn't passing:
function validateAnswers(groupName) {
var formInstance = $('.my-form').parsley();
var isValid = formInstance.validate(groupName);
// Just for debugging:
$.each(formInstance.fields, function(idx, field) {
if (typeof field.validationResult === 'boolean') {
// Validated.
console.log('Passed: ' + field.value);
} else if (field.validationResult.length > 0) {
console.log('Failed: ' + field.validationResult[0].assert.name);
}
});
return isValid;
}
This worked on my very simple form with 'required' radio buttons; no idea how it would work on larger forms with different types of fields and validation requirements.
Any better answers or improvements?
Here's what I did for this type of situation.
var formElements = $('form .elementClass').parsley(); // Get all elements inside your form
// Loop through all the elements found
_.forEach(formElements, function(formElement) { //You can use a regular for loop if you prefer
var errors = ParsleyUI.getErrorsMessages(formElement); //Get the list of errors for this element
if (errors.length) {
// Output the first error in the array. You could loop this too.
console.log(errors[0]);
}
});
It feels a bit ugly, but it gets you what you need.
I am using code in an aspx page (javascript) that is displayed using the sharepoint 2010 UI framework dialog functions.
However, it throws an error. I can't get at the exact details. But here's the code
function DoReject(rejectype) {
rejecttype = rejectype;
this.clientContext = new SP.ClientContext.get_current();
var targetList = clientContext.get_web().get_lists().getByTitle('Applications');
var qs =window.location.search.substring(1);
var arrs = qs.substring(0,qs.indexOf('&',0)).replace('arr=','').split(',');
for (var i = 0; i < arrs.length;i++) {
k = arrs[i];
if (k != null && k != '') {
try {
this.applicant = targetList.getItemById(k);
applicant.set_item('ApplicationStatus', 'REJECTED');
applicant.update();
clientContext.executeQueryAsync(Function.createDelegate(this, this.doNothingReject), Function.createDelegate(this, this.rejectError));
this.applicant = targetList.getItemById(k);
clientContext.load(applicant, 'EMail', 'CrisDBID', 'ApplyJobTitle', 'JobRef', 'BrandId');
clientContext.executeQueryAsync(Function.createDelegate(this, this.DoRejectSuccess), Function.createDelegate(this, this.rejectError2));
}
catch (e) {
alert(e);
}
}
}
}
Note i haven't included the success / error methods, as they are superfluous in this. And the ids return correctly - they are passed into the query string. So the variable k is definitely the id of the list item.
In the error event rejectError, I use the signature
rejectError(e)
Does anyone know how to get the error details from the parameter / whats wrong with the code?
is it possible to call list operations on a page that isn't the native list page using the javascript object model?
thanks in advance

What browser do you get the error in? Is the error consistent between browsers? I would recommend that you debug the javascript and look at the variables at the line before it fails to see what's going on.
On a side note the first snippet you pasted looks like a standard train-wreck so if the code fails there it's likely one of these are undefined (if clientContext, get_web() or get_lists() does not return a value). I don't know anything about Sharepoint UI framework so "list operation" etc doesn't say much to me.
