Service Provider object is becoming null while running the script through commandline

[kjakkam]

In Startup.cs file, created an object for ServiceProvider as below

services.AddSingleton<IRestLibrary, RestLibrary>();
IServiceProvider serviceProvider;
serviceProvider = services.BuildServiceProvider();

During, any of other methods execution in that same Project, trying to get the data of serviceProvider. But that serviceProvider's data is showing as null.

The issue is only happening through the commandline execution. If we try to execute the same scenario through Visual Studio, it is working fine without any issues.

Can you give us any more information? such as a demo?

[kjakkam]

Sure, I will create a sample project, and share the details.

@pengweiqhca, I have created a demo project, and in which the issue reproducing.

Please go through the below demo project
https://github.com/jakkamk4/XUnitTestAutomation

**Issue: **
From CommandPrompt, go to following project execution Path - bin\Debug\net6.0 folder
Execute below command - It will execute - "GetLocationOfTestEmployee" Test case
dotnet test TestProject1.dll

While executing the test case through Comman Prompt, it is throwing System.NullReferenceException at ServiceLocator.cs:line 35
i.e. IServiceProvider is getting null

If we execute same test case through Visual studio, it is executing successfully. The issue is only with CommandPrompt execution.

Note: For more details of execution, you can find the log details of execution in the TestExecutionLogs file under the bin\Debug\net6.0 folder

@pengweiqhca , seeing below error after replacing the [MemberData] attribute with [MethodData] attribute (ex: [MethodData(nameof(TestData.GetLocationObject))])

Error message after running the test case:

@pengweiqhca ,One observation, through command prompt execution, I assumed that - Startup file is not being called first.
