Injection¶

Jan 29, 2017 HtmlTest runner is a unittest test runner that save test results in Html files, for human readable presentation of results. This Package was inspired in unittest-xml-reporting and HtmlTestRunner by tungwaiyip. If you want to run specifically that test function (in this case, testanswer), right click anywhere in the function that you want to test and choose Run 'pytest for (the file name).(the function name)' - so in this case, sample.testanswer. You, similarly, can put your line.

With either of the two methods mentioned above, the variables TEST_APPand TEST_METHOD will be injected into the fake WSGI environment.

TEST_APP will contain a secret key that you define when executing your tests.TEST_METHOD will contain the method used to execute the models. This will eitherbe WebTest if you use the webtest method, or FakeEnv if you use the new_envmethod.

• HtmlTest runner is a unittest test runner that saves results in a human-readable HTML format. This Package was inspired by unittest-xml-reporting and HtmlTestRunner by tungwaiyip and began by combining the methodology of the former with the functionality of the latter. Table of Content.
• Basic example¶ The unittest module provides a rich set of tools for constructing and running tests.

From your model, you can verify the existence of this key and optionally performlogic checks based on this, such as defining a test database as your main objectinstead of using your production database.

Here is an example of determining the existence of this key.:

Warning

You might want to remove these checks in a production environment. The secretkey is there to provide some security in case you forget, but the check doescreate a little overhead.

Note

This is the recommended way of using a test database. There are tworeasons.

1. If you have quite a few functions declared in your models thatrely on your db object, if you want to test these functions, theywill break if you use the copy_db function, since they will referto your actual database in this case.
2. The copy_db function introduces lag time into your testing, sinceit will effectively be creating a brand new database on eachtest function.

Another approach is to use the provided copy_db function, which will make asqlite:memory: DAL instance using the tables provided by your main db object.More info on this in the Fake Environment section.

Testing determines whether software runs correctly based on specific inputsand identifies defects that need to be fixed.

Console Output

Why is testing important?

As software scales in codebase size, it's impossible for a person or evena large team to keep up with all of the changes andthe interactions between the changes. Automated testing is the only provenmethod for building reliable software once they grow past the point of asimple prototype. Many major software program development failures can betraced back to inadequate or a complete lack of testing.

It's impossible to know whether software works properly unless it is tested.While testing can be done manually, by a user clicking buttons or typing ininput, it should be performed automatically by writing software programs thattest the application under test.

There are many forms of testing and they should all be used together. Whena single function of a program is isolated for testing, that is calledunit testing. Testing more than a single functionin an application at the same time is known asintegration testing.User interface testing ensures the correctness of how a user wouldinteract with the software. There are even more forms of testing that largeprograms need, such as load testing, database testing, andbrowser testing (for web applications).

Intallation

Testing in Python

Python software development culture is heavy on software testing. BecausePython is a dynamically-typed language as opposed to a statically-typedlanguage, testing takes on even greater importance for ensuring programcorrectness.

Python testing tools

The Python ecosystem has a wealth of tools to make it easier to runyour tests and interpret the results. The following tools encompasstest runners, coverage reports and related libraries.

See Full List On Github.com

• green is a test runner that haspretty printing on output to make the results easier to read andunderstand.

• requestium merges theRequests library with Selenium to make it easier to run automatedbrowser tests.

• coverage.py is a tool formeasuring code coverage when running tests.

Usage

Mocking resources

Mocking allows you to isolate parts of your code under test and avoidareas that are not critical to the tests you are writing. For example,you may want to test how you handle text message responses but do notwant to actually receive text messages in your application. You canmock a part of the code that would provide a happy-path scenario soyou can run your tests properly. The following resources show you how touse mocks in your test cases.

• Getting Started with Mocking in Pythonprovides a whole code example based on a blog project that showshow to use mock when testing.

• Python Mocking 101: Fake It Before You Make Itexplains what mocking is and is not, and shows how to use the patchfunction to accomplish it in your project.Revisiting Unit Testing and Mocking in Pythonis a follow-up post that expands upon using the patch functionalong with dependency injection.
