After you have executed your first tests with Apptim, you might want to compare the performance of two versions of your app.
We recommend using this feature when you want to compare the performance of TWO SIMILAR TESTS, but executed on different versions of your app. To get better results, you also want to run both tests on the same device, so you remove other variables that may affect the performance results.
For example, you might want to repeat a test you did of a Login in the new version of the app and see if there are any big differences in the performance of that functionality.
Both tests should be similar in duration, so you can then easily compare the graphs showing CPU usage, Memory usage and Network data transfer.
Follow these steps to compare two test sessions in Apptim Cloud:
1) Access your account, select the workspace and app you want to compare.
2) You will see a list of all the test sessions (run by you and/or other users in you workspace).
3) Select two test sessions from the list and click on Compare.
Below is an example of how the performance of Login is on two different build versions of the same app on a Google Pixel 3.
CPU Graphs: Session 1 vs Session 2
Memory Graphs: Session 1 vs Session 2
In the memory graphs, you can compare the Total (PSS) memory used during Session 1 vs Session 2, as well as the Native and Dalvik Heap memory usage in each session.
Network Graphs: Session 1 vs Session 2
In the network graphs, you can compare the amount of data sent (KB) during Session 1 vs Session 2, as well as the amount of data received (KB) during each session.
