+### TUNIT_ENABLE_IDE_STREAMING
+
+Enables real-time output streaming to IDE test explorers (Rider, VS Code, Visual Studio).
+
+```bash
+# Bash/Linux/macOS
+export TUNIT_ENABLE_IDE_STREAMING=1
+
+# PowerShell
+$env:TUNIT_ENABLE_IDE_STREAMING = "1"
+
+# Windows Command Prompt
+set TUNIT_ENABLE_IDE_STREAMING=1
+```
+
+**Default:** Disabled
+
+**Use case:** When running tests in an IDE, this enables real-time streaming of test output (e.g. `Console.WriteLine`) to the test explorer while tests are still running. Without this, output is shown after each test completes.
+
+**Note:** This feature is disabled by default due to known compatibility issues with the Microsoft Testing Platform that can cause test runner crashes in some IDEs. Enable it only if you want real-time output streaming and are not experiencing issues.
