Transform json Files in Azure Pipelines

 In .NET aplication we use the appsettings.json to keep values such as connection string etc for local development mostly. In the context of Azure app servies or containeried envronments etc, we configure mostly app config service (with key vault to manage secrets) to keep our connection information, and any other config values. Howver, sometimes legecy deployments which are still done targeting on premise servers etc might need us to update actual appsetting.josn files or web config files etc. Let's look at how to transform josn files in an Azure pipeline.

Code Unit Test Coverage with Azure Pipelines

 Unit tests are essntial to ensure the code we develop is working as intended. Running the unit tests Azure pipelines is really helpful to not to miss the unit test failures. However, to give afurther assuarance we need to check the coverage of code with unit tests in our projects. Let's look at steps required to obtain a code unit tests coverage report in Azure piplines in  cobertura format.

The expected outcome

The coverage here shows the first library, all code lines (100%) are covered with tests and the the other library has only 22.2% code coverage.

Conditionally Passing Different Values to Template Parameters in Azure DevOps Pipelines

Parameters Azure pipeline template helps to achieve dynamic behaviours in pipeline templates. Passing different values for template parameters based on conditions, via a single usage of teplate will help to reduce duplication of usage of template in the pipeline. Let's look at how to conditionally pass different values to template paramters with a practical example.

The expected behavoir

Let's assume there are three stages in the pipeline.

  • Unit test stage - to build and unit test
  • Build and push Docker image stage
  • Deploy app stage

If we are in develop branch (refs/heads/develop) we want to run unit tests, build dcoker image and depending on both stages want to run a deploy.
