Python Html Test Runner

HTMLTestRunner is an extension to the Python standard library's unittest module. It generates easy to use HTML test reports. See a sample report here. HTMLTestRunner is released under a BSD style license. 14 comments Download. HTMLTestRunner.py (0.8.2) testHTMLTestRunner.py test and demo of HTMLTestRunner.py. Return to my software. A TestRunner for use with the Python unit testing framework. It generates a HTML report to show the result at a glance. # run the test runner.run(mytestsuite).

  • This executes the test runner by discovering all classes in this file that inherit from unittest.TestCase. This is one of many ways to execute the unittest test runner. When you have a single test file named test.py, calling python test.py is a great way to get started. Another way is using the unittest command line.
  • Auto-discovery of test modules and functions. Modular fixtures for managing small or parametrized long-lived test resources. Can run unittest (including trial) and nose test suites out of the box. Python 3.6+ and PyPy 3. Rich plugin architecture, with over 315+ external plugins and thriving community.

Lesson Goals

This lesson uses Python to create and view an HTML file. If you writeprograms that output HTML, you can use any browser to look at yourresults. This is especially convenient if your program is automaticallycreating hyperlinks or graphic entities like charts and diagrams.

Here you will learn how to create HTML files with Python scripts, andhow to use Python to automatically open an HTML file in Firefox.

Files Needed For This Lesson

  • obo.py

If you do not have these files from the previous lesson, you candownload programming-historian-5, a zip file from the previous lesson.

Creating HTML with Python

At this point, we’ve started to learn how to use Python to downloadonline sources and extract information from them automatically. Rememberthat our ultimate goal is to incorporate programming seamlessly into ourresearch practice. In keeping with this goal, in this lesson and thenext, we will learn how to output data back as HTML. This has a fewadvantages. First, by storing the information on our hard drive as anHTML file we can open it with Firefox and use Zotero to index andannotate it later. Second, there are a wide range of visualizationoptions for HTML which we can draw on later.

If you have not done the W3 Schools HTML tutorial yet, take a fewminutes to do it before continuing. We’re going to be creating an HTMLdocument using Python, so you will have to know what an HTML documentis!

“Hello World” in HTML using Python

One of the more powerful ideas in computer science is that a file thatseems to contain code from one perspective can be seen as data fromanother. It is possible, in other words, to write programs thatmanipulate other programs. What we’re going to do next is create an HTMLfile that says “Hello World!” using Python. We will do this by storingHTML tags in a multiline Python string and saving the contents to a newfile. This file will be saved with an .html extension rather than a.txt extension.

Python

Typically an HTML file begins with a doctype declaration. You sawthis when you wrote an HTML “Hello World” program in an earlier lesson.To make reading our code easier, we will omit the doctype in thisexample. Recall a multi-line string is created by enclosing the text inthree quotation marks (see below).

Save the above program as write-html.py and execute it. Use File ->Open in your chosen text editor to open helloworld.html to verify thatyour program actually created the file. The content should look likethis:

Now go to your Firefox browser and choose File -> New Tab, go to thetab, and choose File -> Open File. Select helloworld.html. Youshould now be able to see your message in the browser. Take a moment tothink about this: you now have the ability to write a program which canautomatically create a webpage. There is no reason why you could notwrite a program to automatically create a whole website if you wantedto.

Using Python to Control Firefox

We automatically created an HTML file, but then we had to leave oureditor and go to Firefox to open the file in a new tab. Wouldn’t it becool to have our Python program include that final step? Type or copythe code below and save it as write-html-2.py. When you execute it, itshould create your HTML file and then automatically open it in a new tabin Firefox. Sweet!

Mac Instructions

Mac users will have to specify to the precise location of the .htmlfile on their computer. To do this, locate the programming-historianfolder you created to do these tutorials, right-click it and select “GetInfo”.

You can then cut and paste the file location listed after “Where:” andmake sure you include a trailing slash (/) to let the computer know youwant something inside the directory (rather than the directory itself).

Not only have you written a Python program that can write simple HTML,but you’ve now controlled your Firefox browser using Python. In the nextlesson, we turn to outputting the data that we have collected as an HTMLfile.

Code Syncing

To follow along with future lessons it is important that you have theright files and programs in your “programming-historian” directory. Atthe end of each lesson in the series you can download the “programming-historian” zipfile to make sure you have the correct code. If you are following alongwith the Mac / Linux version you may have to open the obo.py file andchange “file:///Users/username/Desktop/programming-historian/” to thepath to the directory on your own computer.
