-Integration tests targets also have a browser and remote suffix to control which browser to pick and whether to use Grid.

-Supported browsers:
-
-* `chrome`
-* `edge`
-* `firefox`
-* `firefox-beta`
-* `ie`
-* `safari`
-* `safari-preview`
-
-In addition to the [Common Options Examples](#common-options-examples), here are some additional Ruby specific ones:
-* `--test_arg "-eTimeouts"` - test only specs which name include "Timeouts"
-* `--test_arg "<any other RSpec argument>"` - pass any extra RSpec arguments (see `bazel run @bundle//bin:rspec -- --help`)
-
-Supported environment variables for use with `--test_env`:
-
-- `WD_SPEC_DRIVER` - the driver to test; either the browser name or 'remote' (gets set by Bazel)
-- `WD_REMOTE_BROWSER` - when `WD_SPEC_DRIVER` is `remote`; the name of the browser to test (gets set by Bazel)
-- `WD_REMOTE_URL` - URL of an already running server to use for remote tests
-- `DOWNLOAD_SERVER` - when `WD_REMOTE_URL` not set; whether to download and use most recently released server version for remote tests
-- `DEBUG` - turns on verbose debugging
-- `HEADLESS` - for chrome, edge and firefox; runs tests in headless mode
-- `DISABLE_BUILD_CHECK` - for chrome and edge; whether to ignore driver and browser version mismatches (allows testing Canary builds)
-- `CHROME_BINARY` - path to test specific Chrome browser
-- `CHROMEDRIVER_BINARY` - path to test specific ChromeDriver
-- `EDGE_BINARY` - path to test specific Edge browser
-- `MSEDGEDRIVER_BINARY` - path to test specific msedgedriver
-- `FIREFOX_BINARY` - path to test specific Firefox browser
-- `GECKODRIVER_BINARY` - path to test specific GeckoDriver

+# .NET Testing Guide
+
+This guide helps contributors write tests in the Selenium .NET codebase.
+
+## Test Framework
+
+* Tests use NUnit.
+* All tests inherit from `DriverTestFixture`.
+* Test HTML pages accessed via properties like `simpleTestPage`, `javascriptPage`.
+* `WaitFor<T>()` provides waiting with 5-second default timeout.
+
+```csharp
+[TestFixture]
+public class MyFeatureTest : DriverTestFixture
+{
+    [Test]
+    public void ShouldFindElement()
+    {
+        driver.Url = simpleTestPage;
+        IWebElement element = driver.FindElement(By.Id("foo"));
+        Assert.That(element.Text, Is.EqualTo("expected"));
+    }
+
+    [Test]
+    [IgnoreBrowser(Browser.Safari, "Safari doesn't support this")]
+    public void ShouldDoSomething()
+    {
+        // Skipped on Safari
+    }
+}
+```
+
+## Running Tests
+
+Bazel creates test targets for each browser. Always use `--pin_browsers`.
+
+```shell
+bazel test //dotnet/test/common:AllTests --pin_browsers=true  # Default browser (Firefox)
+bazel test //dotnet/test/common:AllTests-chrome --pin_browsers=true
+bazel test //dotnet/test/common:AllTests-firefox --pin_browsers=true
+bazel test //dotnet/test/common:AllTests-edge --pin_browsers=true
+
+# Additional Arguments
+bazel test //dotnet/... --flaky_test_attempts=3 --pin_browsers=true
+bazel test //dotnet/... --test_output=all --pin_browsers=true
+```
+
+## Attributes
+
+### Skipping Tests
+
+| Attribute | When to Use |
+|-----------|-------------|
+| `[IgnoreBrowser(Browser.X, "reason")]` | Skip test for specific browser |
+| `[IgnorePlatform("windows", "reason")]` | Skip test on specific OS |
+| `[IgnoreTarget("net8", "reason")]` | Skip test on specific .NET version |
+| `[Ignore("reason")]` | Skip test entirely (NUnit built-in) |
+
+```csharp
+[Test]
+[IgnoreBrowser(Browser.Safari, "Safari doesn't support multiple instances")]
+[IgnoreBrowser(Browser.IE, "IE is flaky")]
+public void TestWithMultipleDrivers()
+{
+}
+
+[Test]
+[IgnorePlatform("windows", "Thread time not supported")]
+public void TestLinuxOnly()
+{
+}
+```
+
+Browser values: `Browser.Chrome`, `Browser.Firefox`, `Browser.Edge`, `Browser.Safari`, `Browser.IE`, `Browser.Remote`, `Browser.All`
+
+### Driver Lifecycle
+
+| Attribute | When to Use |
+|-----------|-------------|
+| `[NeedsFreshDriver(IsCreatedBeforeTest = true)]` | Fresh driver before test |
+| `[NeedsFreshDriver(IsCreatedAfterTest = true)]` | Fresh driver after test |
+
+```csharp
+[Test]
+[NeedsFreshDriver(IsCreatedBeforeTest = true, IsCreatedAfterTest = true)]
+[IgnoreBrowser(Browser.Safari, "Safari doesn't support multiple instances")]
+public void TestRequiringFreshDriver()
+{
+    IWebDriver driver2 = EnvironmentManager.Instance.CreateDriverInstance();
+    try
+    {
+        // Test with multiple drivers
+    }
+    finally
+    {
+        driver2.Quit();
+    }
+}
+```
+
+## Helpers
+
+From `DriverTestFixture`:
+
+| Member | Description |
+|--------|-------------|
+| `driver` | Current WebDriver instance |
+| `simpleTestPage`, `javascriptPage`, etc. | Test page URLs |
+| `WaitFor<T>(condition, timeout)` | Wait for condition (default 5s) |
+| `CreateFreshDriver()` | Create new driver instance |
+
+From `EnvironmentManager.Instance`:
+
+| Member | Description |
+|--------|-------------|
+| `CreateDriverInstance()` | Create additional driver |
+| `CreateDriverInstance(options)` | Create driver with custom options |
+| `Browser` | Current browser enum value |
+
+## Test Organization
+
+```
+dotnet/test/
+├── common/                    # Cross-browser tests
+│   ├── DriverTestFixture.cs   # Base class
+│   ├── CustomTestAttributes/  # Custom NUnit attributes
+│   └── *Test.cs              # Test files
+└── support/                   # Support library tests
+```
+
+## Build Files
+
+* Adding tests shouldn't require Bazel changes—tests are picked up via glob.
+* Make sure `*Test.cs` files are in a directory with `dotnet_nunit_test_suite` in BUILD.bazel.
