在 Azure Devops yaml 构建管道中运行时如何为 SSDT 单元测试指定连接详细信息

Question

I am using SSDT unit tests for my database project. They run no problem from Visual Studio.

I would like these tests to run when I run my build pipeline on Azure DevOps, but when it is unable to connect. I get the following error:

System.Data.SqlClient.SqlException: System.Data.SqlClient.SqlException: 110003;Invalid user or password.

The yaml for my test is as follows:

- task: VSTest@2
  inputs:
        testSelector: 'testAssemblies'
        testAssemblyVer2: |
          **\*test*.dll
          !**\*TestAdapter.dll
          !**\obj\**
        searchFolder: '$(System.DefaultWorkingDirectory)'

Is there anything in particular that needs to go in the app.config file to get this to work? Note: I'm using SQL authentication.

If the SSDT unit tests connects to the database server on your local machine, the azure devops pipeline will fail, for the hosted agents cannot communicate with your local machine.

In this case you should create a self-hosted agent on your local machine, and run your pipeline on the self-hosted agent by defining the pool as your local agent pool in yaml pipeline.

If you are using other cloud database server like azure sql server. You can check if the connectionString in App.config is correct, and provide the correct User ID and Password . The connectionString in app.config file is like below example

If you want to avoid storing sensitive information in a connection string in app.config. You can store the connectionString in a secret variable in your pipeline.

And use tokens connectionString="#{sqlDbTestConnectionString}#" in app.config in place of real connection strings.

Then add replace token task before VsTest task in your pipeline to replace the tokens #{sqlDbTestConnectionString}# in app.config with the real connectionString defined in secret variable.
