what's diffrence between page.evaluate and page.waitForFunction in puppeteer
Differences:
page.evaluate will run the code once and return data.
page.waitForFunction will run the code repeatedly until the code returns truthy values.

System.out.println("Check1");
expect(mockobject.function(parameters)).andReturn("hello";
System.out.println("check2***************************");
replay(mockobject);
While executing the test, the mockobject.function(parameters) executes and call goes to the method.Debugging using the system out, it checks inside the function is also displayed in console.
Why is it so? The expect() doesn't allow the call to be made to the desired function?
Assuming mockobject is a mock created with mock() or createMock() and not partialMockBuilder(), this can't happen unless function is final.
I am working in node and typescript. I have a controller and a repository. I can log the data out all over the place EXCEPT at the return from the repo. Of course, the controller gets back nothing. Here are the pastebins:
package.json
users_controller.ts
users_repository.ts
This is not the correct way to use Promises. The getUsers() method is called and returns before the Promise has a chance to resolve. The quickest way to fix it is to return the Promise from the getUsers() method or use async/await. Essentially, all of the logic that you have to update the userModels value happens after the function has already returned an empty array.
In Javascript, the following code will execute only once, but in Google Apps Script it executes twice (obviously the body and script tags would be omitted):
<body>
<script>
hi();
function hi() {
alert('hi')
}
</script>
</body>
In other words, in GoogleApps script merely defining a function invokes it. The following in Code.gs executes with undefined arguments passed to it.
function createQuery(keywords, dateRange) {
}
How can I define functions without them being called? Pointers to the docs would be helpful. I have scoured them without success.
In GAS, you save and test functions using the toolbar at the top. By virtue of telling the function to run using the toolbar, you are calling the function. Any triggers that you have will also call it to run without 'calling' inside the code.
You can more minutely determine how and when a function runs by calling it later in the code. This can be done in nested functions or inside of other functions. Regardless of where you are defining the function, eventually you will have to either create a trigger or use the toolbar to run the function.
I'm not sure how you are experiencing a double call seeing as your reference code is not very in-depth. Keep in mind that to execute the script at all, you would have had to either set a trigger or run it yourself in which you are adding in an execution. If you execute code that tells itself to execute that same code, you would incur an infinite loop.
Users will be able to more accurately understand your question and issue and thus answer them should you provide more data and references. You may also want to read the references and guides on the basics of GAS and its use of Javascript.
Is there a way to check if a function has been called from a ExUnit test case? I have a function that calls IO.puts and I would like to test and verify that something is being outputted to STDOUT via a test case.
I saw this: http://erlang.org/pipermail/erlang-questions/2005-July/016259.html. But I was hoping there might be a simpler way of doing this with ExUnit.
Is there a way to check and see if my function calls IO.puts? Or at least check and see if something has been sent to STDOUT?
If you just want to test the STDOUT via a test case, I think CaptureIO can be used.
The following has the spec and sample code.
https://hexdocs.pm/ex_unit/master/ExUnit.CaptureIO.html
You could mock the method calls using some mocking libraries, but for STDOUT, the above one would be simpler approach.

I am writing javascript code to access Google Drive. The code examples show calls like:
gapi.client.load('drive','v2',callbackfunction);
How do I check to see that this call was successful?
I have tried:
result = gapi.client.load('drive','v2',callbackfunction);
But result is undefined.
There is no result to be returned from that call. It's simply loading a library. When the library has finished loading the callback will be called.
