Accelerated Continuous Testing with Test Impact Analysis – Part 2

The previous post introduced how – for a given code commit – TIA will select and run only the relevant tests required to validate that commit. Thus, without sacrificing quality, both the testrun and its enclosing CI definition will complete faster. Here is how that translated to reality for one of our teams: The top… Read more

Visual Studio Test Platform, MSTest V2 – Transparent Development

Transparent development enables collaboration. When we open sourced the Visual Studio Test Platform and the MSTest Test Framework “MSTest V2”, we shared out links to issues, implementation and our roadmap. Here are all the links (including links to groomed backlogs and RFCs) for your convenience: Visual Studio Test Platform: Implementation: https://github.com/Microsoft/vstest Docs: https://github.com/Microsoft/vstest-docs Issues: https://github.com/Microsoft/vstest/issues… Read more

MSTest V2 is open source

As promised, we announced the open sourcing of MSTest Test Framework “MSTest V2”. The community now has a fully supported, open source, cross-platform implementation of the MSTest V2 portfolio with which to write tests targeting .NET Framework, .NET Core and ASP.NET Core on Windows, Linux, and Mac. Here are the public repositories on GitHub where the project… Read more

Open Source Scanning in Visual Studio Team Services with WhiteSource Bolt

Most organizations today consume open source software in their development projects. The reuse of components enables great productivity gains. However, this practice has an unintended consequence: you can reuse security vulnerabilities or violate licenses without realizing the risk. I wrote about this in an article in MSDN Magazine on Rugged DevOps. For users of VSTS, there… Read more

Accelerated Continuous Testing with Test Impact Analysis – Part 1

Continuous Testing in DevOps In older testing strategies, large software changes were tested as a complete product after a so called “release to QA”, running almost all tests just before release. We know the downsides to that. On the other hand, DevOps is all about a fast development to delivery pipeline and continuous delivery of… Read more

MSTest V2 – Now and Ahead

Evolving the Visual Studio Test Platform – Part 3: .NET Core, convergence, and cross-plat

[This is the 3rd post in the series on evolving the Visual Studio Test Platform. You can read the earlier posts here: Evolving the Visual Studio Test Platform – Part 2, Evolving the Visual Studio Test Platform – Part 1] As .NET Core draws an ever-growing community of developers with existing assets and experiences, it… Read more

Parallel Test Execution

An early post on Parallel Test Execution drew attention to its subtle semantics. Three considerations directly contributed to that (1) Reach (2) Composability (3) Non-disruptive roll out. The Visual Studio Test Platform is open and extensible, with tests written using various test frameworks and run using a variety of adapters. To reduce on-boarding friction, the… Read more

Announcing MSTest V2 Framework support for .NET Core 1.0 RTM

MSTest V2 is now supported on .NET Core 1.0 RTM. API changes in .NET Core 1.0 leading up to RTM (see #7754), were blocking users of the MSTest V2 packages we had released for .NET Core 1.0 RC2. Not any more (see #10713), we are pleased to note. This continues to be a preview release, and… Read more
