sorry, I dont understand this test. Could you explain it to me? why this becomes the output and why is the module invalid? Is it because it haz an additional folder?

First of all, we based our tests on our understanding of the code. We don't know exactly how pip builds the structure of a package.
- The first test case was not necessary, so we decided to remove it.
- The second one was called as a "valid_package" because its "top_level.txt" file has one module named "valid_package" that is not in our code's blacklist (which is a variable called ignore with value
["tests", "_tests", "egg", "EGG", "info"]) and also has a module named "tests" that is in that blacklist. - The last test case makes sure that "top_level.txt" files that are inside a folder that starts with "EGG" are not considered.
We tried to understand the code's behavior by reading "setuptools" documentation (link), but we did not understand much. It requires a lot of reading and time for understanding.
If you think it's okay for us to use our time to study this and then validate if it's right, that is okay.

Could you elaborate a bit more as to why the first test was unnecessary?

I see, I wasn´t expecting it to be that convoluted. I will get back to you as to what we should do, for now just fix the double import and focus on the other tasks

Also, you should push to next, not master |

@willianrocha could you take a look at PR #384 also? It seems related to this test, I would like your opinion about the issue, are non top_level pip packages something compliant with how pip works and the documentation? if so it seems one of the test cases implemented in this test could be a problem |

@alan-barzilay Packages that are in the "EGG" format have the "top_level.txt" file, but others don't. For example, pandas is a package in "dist.info" format and it does not have the "top_level.txt" file, but it has the "METADATA" file mentioned in the PR you just said. I don't know which one is compliant or not, but it seems to me that maybe our code is not getting all information it is looking for... In the case of pandas, for example, it would not get the package from the "top_level.txt" and would continue running... Also, in the EGG format, the "PKG-INFO" file seems a lot like the "METADATA" file from "DIST-INFO" format. Obs.: it looks like EGG packages are deprecated... Maybe we could handle both types of distribution... |
