Code coverage in PyCharm allows you to perform on-the-fly line coverage measuring for your code with low runtime overhead. In general, line coverage answers the question, 'Was this line of code executed during unit testing simulation?'
Code coverage results are displayed in the Coverage tool window, in the Project view of the Project tool window, and in the editor. The tool windows show the following information:
For a directory: the percentage of the covered classes and lines.
For a file: the percentage of the covered lines.
When a file is opened in the editor, each line is highlighted with regard to its code coverage status:
Lines executed during simulation are marked green.
Lines not executed during simulation are marked red.
The coverage measurement results comprise a coverage suite. You can have the results of a new simulation merged with any existing suite. In this case, a line will be considered covered if it is covered by at least one of the simulations.
A coverage suite is generated every time a test or application with code coverage measurement is executed. It is possible to have an unlimited amount of coverage suites.
Run with code coverage
General steps for using code coverage in a project
Specify how you want to process the coverage results.
Create tests for the target code, if you are going to measure code coverage for testing.
Configure code coverage measurement in the desired run/debug configuration.
Run with coverage, using the dedicated command from the main menu Run | Run with Coverage, or click the Run with Coverage button .
Once the run with coverage has been executed, you can perform the following actions:
Use the various coverage suites.
View code coverage data.
Generate code coverage report.
PyCharm is one of the most popular Python IDEs. There is a multitude of reasons for this, including the fact that it is developed by JetBrains, the developer behind the popular IntelliJ IDEA IDE that is one of the big 3 of Java IDEs and the “smartest JavaScript IDE” WebStorm. Having the support for web development by leveraging Django is yet another credible reason.
There are a galore of factors that make PyCharm one of the most complete and comprehensive integrated development environments for working with the Python programming language.
Before proceeding further into exploring the know-how of PyCharm i.e., features, installation, and pros & cons, let’s first get a brief introduction to PyCharm.
What is PyCharm?
Available as a cross-platform application, PyCharm is compatible with Linux, macOS, and Windows platforms. Sitting gracefully among the best Python IDEs, PyCharm provides support for both Python 2 (2.7) and Python 3 (3.5 and above) versions.
PyCharm comes with a plethora of modules, packages, and tools to hasten Python development while cutting-down the effort required to do the same to a great extent, simultaneously. Further, PyCharm can be customized as per the development requirements, and personal preferences call for. It was released to the public for the very first time back in February of 2010. In addition to offering code analysis, PyCharm features:
- A graphical debugger
- An integrated unit tester
- Integration support for version control systems (VCSs)
- Support for data science with Anaconda
What is PyCharm used for?
The main reason Pycharm for the creation of this IDE was for Python programming, and to operate across multiple platforms like Windows, Linux, and macOS. The IDE comprises code analysis tools, debugger, testing tools, and also version control options. It also assists developers in building Python plugins with the help of various APIs available. The IDE allows us to work with several databases directly without getting it integrated with other tools. Although it is specially designed for Python, HTML, CSS, and Javascript files can also be created with this IDE. It also comes with a beautiful user interface that can be customized according to the needs using plugins.
What is an IDE?
PyCharm is an extremely popular Python IDE. An Integrated Development Environment or IDE features a code editor and a compiler for writing and compiling programs in one or many programming languages.
Furthermore, an IDE comes with a galore of features that facilitate comprehensive software development. As an IDE allocates different colors to different programming entities, typically known as syntax highlighting, it becomes more accessible to:
- Differentiate between various programming entities, such as a class and a function, and to spot them.
- Look for the wrong keywords.
- Read and comprehend the code.
Most IDEs feature an auto-complete feature that produces suggestions when writing code. This makes writing code more efficient, quick, and less prone to errors and typos. Other standard features offered by a modern IDE are:
- Project editor window for efficiently managing and organizing files necessary for a program/project.
- Inspecting the output of the code written using the output window
- Suggestions for resolving errors and warnings
- A range of modules and packages readily available at a single place
PyCharm Pricing Model
PyCharm is offered in three variants:
- A freemium version dubbed The Community Edition available under the Apache License.
- A commercial version labeled Professional Edition available under a proprietary license.
