My goal for the third week of 0.4 was to put the finishing touches on the function I've been writing, then write some tests.
Writing tests
The testing suite of the project takes advantage of a photo viewer called feh, which is only available on Linux systems. I created a Ubuntu VM and attempted to run my tests. I ran into a host of issues, detailed here. Apparently Ubuntu couldn't display the images fast enough for the tester. Taking the project owner's advice, I installed Lubuntu which finally ended up working.
Pull request
After all of that troubleshooting with the testing suite, I was finally able to create my PR. The project owner requested some minor changes, which I quickly addressed and pushed the fixes for. At the time of writing this though (December 10, 2021), he hasn't gotten back to approve those changes.
Run down
The passed world's position is calculated using the row and column values from worlds.json. Using the position, the scroll bar is clicked to attempt to get as close to the world as possible. If the world is not visible, the list will repeatedly scroll down a "tick" and the world will be searched for again. Once the world is found, it is clicked and we wait until the "Current world" text at the top of the world switcher changes. If it doesn't change before reaching the timeout time, false is returned.
Example
behavior.switch_worlds_logged_in("382")
Outcomes
Working on this issue was a rollercoaster for me. I had a bunch of issues implementing my original idea. The scroll bar just did not want to cooperate, which I could not foresee. I ended up adding CV to click on the world and the scroll function from pyautogui to find it, if it was off the screen from the scroll bar's inconsistent behaviour.
The main takeaway I have from release 0.4, is that there will always be unforeseen issues. I never would have thought the scroll bar would be so inconsistent. Luckily, I was able to solve the problem with the help of the project owner and some friends.
