If you’re an avid user of MSTest and Serilog, you might have stumbled upon a frustrating issue where your console output doesn’t seem to be working as expected. Don’t worry, you’re not alone! In this article, we’ll delve into the world of MSTest and Serilog, exploring the reasons behind this issue and providing step-by-step instructions to resolve it.
What is MSTest?
MSTest is a testing framework developed by Microsoft, allowing developers to create and run tests for their .NET-based applications. It provides a set of attributes and classes that enable you to write unit tests, integration tests, and other types of tests.
What is Serilog?
Serilog is a popular logging library for .NET applications. It provides a simple, fast, and flexible way to log events, exceptions, and other important information. Serilog is widely used in conjunction with MSTest to log test execution and debug information.
The MSTest Serilog Console Issue
When using MSTest and Serilog together, you might encounter an issue where the console output is not displayed or is incomplete. This can be frustrating, especially when you’re trying to debug your tests or troubleshoot issues. The root cause of this problem lies in the way MSTest and Serilog interact with the console.
MSTest redirects the console output to its own internal buffer, which is not accessible by Serilog. As a result, Serilog is unable to write to the console, causing the issue.
Resolving the MSTest Serilog Console Issue
Don’t worry, resolving this issue is easier than you think! Here are the steps to follow:
Step 1: Install the Serilog.Sinks.Console NuGet Package
First, ensure you have the Serilog.Sinks.Console NuGet package installed in your test project. You can do this by running the following command in your Package Manager Console:
Install-Package Serilog.Sinks.Console
Step 2: Configure Serilog to Write to the Console
In your test project, add the following code to configure Serilog to write to the console:
using Serilog;
class MyTestFixture
{
[TestInitialize]
public void Initialize()
{
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.WriteTo.Console(theme: AnsiConsoleTheme.Code)
.CreateLogger();
}
}
Step 3: Redirect the Console Output
To redirect the console output, you’ll need to use the `ConsoleOutput` class provided by MSTest. Add the following code to your test class:
using Microsoft.VisualStudio.TestTools.UnitTesting;
class MyTestFixture
{
[TestInitialize]
public void Initialize()
{
ConsoleOutput.Instance.Listeners.Add(new ConsoleOutputListener());
}
}
Step 4: Update Your Test Methods
Finally, update your test methods to use the `ConsoleOutput` class to write to the console:
[TestMethod]
public void MyTest()
{
ConsoleOutput.Instance.WriteLine("Hello, world!");
// Rest of your test code
}
Troubleshooting Tips
If you’re still experiencing issues, here are some troubleshooting tips to help you resolve the problem:
- Ensure you have the correct NuGet packages installed.
- Verify that your Serilog configuration is correct.
- Check that your test project is configured to use the correct framework (e.g., .NET Framework or .NET Core).
- Try running your tests in a different environment (e.g., command line, Visual Studio) to isolate the issue.

Frequently Asked Question
Got stuck with MSTest Serilog Console issue? Don’t worry, we’ve got you covered! Here are some frequently asked questions and answers to help you troubleshoot the issue:
Why am I not seeing any logs in the console when running MSTest with Serilog?
Make sure you have configured Serilog to write logs to the console. You can do this by adding the `WriteTo.Console` sink in your Serilog configuration. Also, ensure that the log level is set to a level that allows logs to be written to the console.
I’m using a test framework like MSTest, why are my logs not showing up in the console?
MSTest can sometimes swallow console output, including logs. Try setting the `ConsoleOutput` property to `true` in your test settings to enable console output.
How can I configure Serilog to write logs to a file instead of the console?
To write logs to a file, you can add the `WriteTo.File` sink to your Serilog configuration. You’ll need to specify the file path and any additional settings, such as the file name and rolling interval.
I’m using a CI/CD pipeline, why are my logs not showing up in the console output?
CI/CD pipelines often run tests in a headless environment, which means console output might not be visible. Consider using a logging framework that supports writing logs to a file or a centralized logging service, like ELK or Splunk.
What are some common mistakes to avoid when configuring Serilog with MSTest?
Common mistakes include forgetting to configure the Serilog logger, incorrect sink configuration, and not setting the log level correctly. Make sure to review your configuration and test settings carefully to avoid these mistakes.
