I ran TiingoServiceTest in debugger mode and this was the generated stacktrace.
The assertion failed error implied my code had not cleared a test condition. As per the stacktrace, it originated from line 85 of the test file. I have gone through the test file and manually checked the values being tested by adding a breakpoint. All of them are empty.
My question is, what exactly is this section of code doing? I cannot understand that and without doing that I cannot see where my logic is failing. The same logic was working for me in Module 4 but its breaking here and I got no idea why that is happening, since I cannot understand what is being tested here. Please help.
