Let’s look into the new unit test system in detail.
\n<\/p>\n

Creating projects<\/h2>\n

This one is really straight-forward.\u00a0We have simply added a new option called “Unit test project” to\u00a0Embedded, Linux and Android project wizards.\u00a0It automatically downloads the selected\u00a0test framework (CppUTest and GoogleTest are supported out-of-the-box) and creates a project with a few predefined tests demonstrating how to use the selected framework:<\/p>\n

\"testprj\"<\/a><\/p>\n

On Android VisualGDB offers a choice between running the C++ tests inside a Java\u00a0App (the main activity will\u00a0run the tests and exit the app) or\u00a0in a stand-alone Android executable that is very lightweight, quick to build\u00a0and deploy and does not require the Java layer:\"androidtest\"<\/a><\/p>\n

Running and debugging tests<\/h2>\n

VisualGDB\u00a0transparently integrates the C++ testing functionality into the regular Visual Studio GUI (supported\u00a0starting from Visual Studio 2012), so you can use the regular Test Explorer window and the Test menu to\u00a0browse, run or debug your tests.\u00a0Like in C# tests, the failed test will display\u00a0what triggered the failure\u00a0along with a call stack that will help you quickly pinpoint the cause of the failure.<\/p>\n

We’ve also made it\u00a0very easy to debug\u00a0your tests: just select\u00a0one or more failed tests in the Test Explorer, right-click and select “Debug”. \u00a0This will automatically launch\u00a0debugging of the selected tests and once\u00a0a\u00a0failure is reported by the test, VisualGDB will intercept it and allow you to investigate:\"testfail\"<\/a>Once you click “Break”, VisualGDB\u00a0will\u00a0stop the debug session at the time when the error happened allowing you to investigate what is going on. If the preprocessor macros used by the test framework make things unclear, you can use the “Preprocess selected lines” command to quickly expand them in-place:\"faildetail\"<\/a><\/p>\n

TinyEmbeddedTest<\/h2>\n

To support unit testing on very small embedded devices that don’t have a lot of resources we have\u00a0created a\u00a0miniature testing framework that\u00a0uses the\u00a0CppUTest<\/a> syntax and minimizes the amount of\u00a0code that needs to be run on the device. It has a FLASH memory\u00a0footprint of\u00a0less than 10KB and\u00a0is supported out-of-the-box by VisualGDB:\"tinytest\"<\/a><\/p>\n

<\/h2>\n

Customizing tests<\/h3>\n

The VisualGDB test system is designed to be easily extendable to support other test frameworks and platforms. \u00a0This post<\/a>\u00a0gives a detailed\u00a0explanation\u00a0of the related settings that allow using VisualGDB with any other C++ test framework.<\/p>\n
