Start coverage monitor by running the command vsperfcmd /start:coverage /output:”My_coverage”.Ģ. To get code coverage for Windows Azure service, you need to first instrument the service by using the steps below.ġ. Install dev fabric (Windows Azure SDK latest).Install Microsoft Visual Studio 2010/2012.You can follow the steps belo9w to set up the environment and collect the code coverage: Pre-requisiteĪs a pre-requisite, you need to install the items below: Microsoft VSTS allows you to follow a set of steps to achieve detailed, line-by-line statistics for which code has been tested and not tested. Steps to Achieve Code Coverage Using VSTSĬode coverage data for Azure services can easily be collected by running test cases on dev fabric using Microsoft VSTS. ![]() Improve overall test case quality to test untested code or a complex code piece of product.Easily find dead or unused code, which is not related to the actual requirement.Help in defining the granular level testing strategy to test assembly, namespace and class, etc.Improve the quality of the product to identify the areas that are not covered by test case execution.Benefit of Code CoverageĬode coverage for Windows Azure services is a bit new in the technology world but Microsoft provides a simple and effective way to perform code coverage analysis using VSTS to get all the benefits of it some of them are as follows: In this article, we’ll discuss how code coverage can be done for Windows Azure Service using Microsoft Visual Studio Team Suite (VSTS). If after executing all the test cases still you find that there are code blocks and lines available that are not covered, it means the program or product has not been thoroughly tested.Ĭode coverage helps to improve the quality of testing you can identify the areas where more focus is required to increase the coverage and deliver a quality product. Also, it helps to analyze which parts of a program or product are tested and which are not covered or partially covered by the collection of test cases.

By following the steps outlined in this blog post, you can set up code coverage analysis on your local machine and start improving your test coverage content and product recommendations are editorially independent. While Visual Studio Enterprise offers a built-in code coverage feature, there are plenty of open-source packages and extensions that allow you to get the same functionality without the need for an expensive license. In conclusion, code coverage analysis is an essential tool for any developer looking to build high-quality, maintainable code. Fine Code Coverage will automatically detect the coverage data and display it in the Fin Code Coverage window. All you need to do is install the extension and run your tests. This extension works with both the Community and Professional editions of Visual Studio. Fine Code Coverage adds a window to Visual Studio that shows you which lines of code are covered by your tests. In Visual Studioįinally, if you’re using Visual Studio, you can install the Fine Code Coverage extension to get similar functionality to Coverage Gutters. You can open this report in your web browser to see detailed information about your test coverage, including which lines of code are covered, which ones are not, and where you need to focus your efforts to improve your test coverage. This will create an HTML report in a directory called “.coverage”. This file can be read by Coverage Gutters, allowing you to see the coverage information directly in the code editor. The second flag, -p:CoverletOutput=./, tells Coverlet to save the report to a file called. The first flag, /p:CoverletOutputFormat=lcov, tells Coverlet to generate a report in the lcov format instead of the default coverage.json. To make Coverage Gutters work with Coverlet, you need to run your tests again with two additional flags. ![]() Coverage Gutters is a popular extension that adds coverage information to the code editor’s gutter. The first thing we can do is install the Coverage Gutters extension in Visual Studio Code. ![]() However, this file is not human-readable, so the next step is to use extensions and other packages to make this data consumable by a human. It will also generate a coverage.json file that contains all the coverage data you need. This will print a nice table summary of your code coverage to the console.
