You may remember that MATLAB can generate code coverage information in the Cobertura format now. Been able to since R2017b. This is great since this allows us to leverage a richer ecosystem of capabilities and tools that are out there. ... read more >>

Coverage. It's all good. Health care coverage is good. Cell phone coverage is good. Even cloud coverage can provide a nice break from the intensity of the sun's rays sometimes. It should come then as no surprise that good code coverage also gives us that nice warm fuzzy feeling, like... read more >>

Ah the joys of a new release! R2017b is now out and packed with some great new features. So here I go, heading out to an excitement fueled upgrade-mania when lo and behold, my glee is rudely interrupted when I see my code is broken in the new release.... read more >>

Last time we saw that the new version 13 YAML output can provide a richer CI system experience because the diagnostics are in a standard structured format that can be read by a machine (the CI system) and presented to a human (you) much more cleanly.... read more >>

Diagnostics. They are the secret sauce of an effective test framework and we certainly take our job seriously at providing diagnostics that are not a little too hot or a little too cold, but juuuuusssst the right information to present, especially when encountering a failure. The reason this is so... read more >>

Today I wanted to share some fun I've been having with customizing the emails sent from my Jenkins builds. This was inspired by Narendra's comment on a previous post. So, getting to it, I took a quick look after reading the comment and found the Email-ext plugin that enables customization of the emails that are sent to administrators and code committers (offenders?) for failing or unstable builds. Out of the box, this plugin sends an email that lists the failing tests that were encountered. While this is nice, it doesn't pass muster in my book. Why? ... read more >>

Goodness time flies! It has been a while since we've had a blog update, While I really would like to keep the conversation we have going on here moving, this is how I would like you to envision what I have been up to recently:... read more >>

Last post we explored connecting MATLAB to Jenkins, running tests, and ensuring the build fails upon any test failure. We leveraged the TestResult array returned from the test run in order to exit MATLAB with a non-zero exit status code to communicate to Jenkins when needed that the build should fail.... read more >>

Hi there. I am super excited to introduce our new Developer Zone blog! I work in a group at MathWorks that is responsible for building the infrastructure and architecture that we require as a company to deliver software that is of high quality, on schedule, and meets customer requirements. In short, we develop the build, test, and integration tools needed to produce production grade software on multiple platforms and using many different technologies. My specific team is focused on test infrastructure and are the primary developers of MATLAB's unit test framework.... read more >>
