Add import time test

[bgee]

Add import speed test using bin/test_import.py.

[asmeurer]

Add a space after the 🕙 to make the bold work.

[asmeurer]

This isn't even right. It should be bin/test_import

[asmeurer]

You should parse the output of test_import and use the result from there (with the +-).

@asmeurer Just did. sympy/sympy#1924
Also, test_import just assumes it will be called inside sympy/. Should I fix this in sympy? No big deal though.
(Sorry I accidentally closed this pull request. )

[asmeurer]

Yes, fix it. Look at all the other various functions to see how (e.g., bin/test).

[asmeurer]

Could you add a flag to make this configurable (both command line and config file)?

[bgee]

@asmeurer Yes. I will try to finish this before tomorrow afternoon. What will be a good flag? We already have -t. Should we make it default to run?
Also, I saw the test you put has a line Test command: ** -V**. It's not showing up on my machine. Did I break anything?

[asmeurer]

No, I tested with -t " -V" so that it wouldn't actually run the tests, so that it would come up quickly.

[asmeurer]

I guess call it --import-time or --no-import-time (depending on what you make the default).

[bgee]

@asmeurer I use --no-import-time for command line option and no_import_time = false/true in config file.

[asmeurer]

This looks fine. I want to just wait a little bit (maybe a few days) to see if anyone else has any comments.

[asmeurer]

By the way, you can test comments without spamming a pull request by using --no-comment (-n is also a good idea, since there's no point in uploading the reviews either), then pasting the comment output that is printed to the terminal in an issue in some test GitHub repository (I use https://github.com/asmeurer/GitHub-Issues-Test/issues).

@asmeurer Sounds good. I will also start working on that bin/test_import directory fix.
