I have two projects in the solution.
A sample integration test class is here.
public class CustomersControllerTests : IClassFixture<WebApplicationFactory<WebAPIProject.Startup>>
{
public CustomersControllerTests(WebApplicationFactory<WebAPIProject.Startup> factory)
{
_httpClient = factory.CreateClient();
_customerRepository = factory.Services.GetService<ICustomerRepository>();
}
}
I developed the integration tests using the following article.
https://docs.microsoft.com/en-us/aspnet/core/test/integration-tests?view=aspnetcore-3.1
All tests ran fine in Visual Studio. So the integration tests project is put into a Azure DevOps pipeline.
Here are the tasks in the Agent job.
All tests are failed during execution and here is the stack trace for one of the tests.
System.InvalidOperationException : Solution root could not be located using application root D:\a\r1\a\_ReleaseManagement.API.IntegrationTests-CI\drop\ReleaseManagement.IntegrationTests\Release\.

Any help on how to resolve this issue so the tests can be executed in azure devops pipeline?
I have made the following changes to resolve the posted issues.
public class CustomWebApplicationFactory : WebApplicationFactory<WebAPIProject.Startup> {
protected override void ConfigureWebHost(IWebHostBuilder builder)
{
builder.UseContentRoot(AppContext.BaseDirectory);
base.ConfigureWebHost(builder);
}
}
Use the CustomWebApplicationFactory in the integration tests.
public class CustomersControllerTests : IClassFixture<CustomWebApplicationFactory>
{
public CustomersControllerTests(CustomWebApplicationFactory factory)
{
_httpClient = factory.CreateClient();
_customerRepository = factory.Services.GetService();
}
}
