From 50376ba31c4a2bed956b763c4dd161efcaaf8aa0 Mon Sep 17 00:00:00 2001 From: jbrinkman Date: Thu, 24 Jul 2025 17:06:13 -0400 Subject: [PATCH 1/3] feat: Add comprehensive workflow tests with configuration files - Create sample configuration files for different use cases: - config-strict-breaking-changes.json: Strict breaking change detection - config-lenient-changes.json: Lenient change handling with mappings - config-namespace-filtering.json: Namespace and type filtering - config-malformed.json: Invalid JSON for error testing - config-invalid-format.json: Invalid configuration values - Add WorkflowTests.cs: Integration tests for complete workflows - Test different configuration scenarios - Validate command execution with various settings - Test error handling for invalid inputs - Verify exit codes and error messages - Add CliWorkflowTests.cs: CLI integration tests using actual executable - Test end-to-end CLI workflows - Validate command-line argument processing - Test different output formats - Verify error handling in realistic scenarios - Add ConfigurationWorkflowTests.cs: Configuration file validation tests - Test configuration loading and validation - Test configuration serialization/deserialization - Verify configuration merging with command-line overrides - Test error handling for malformed configurations Addresses requirements 3.1, 3.2, 6.1, 6.2, 7.1 for comprehensive workflow testing with configuration files. --- .../Integration/CliWorkflowTests.cs | 427 ++++++++++++++++++ .../Integration/ConfigurationWorkflowTests.cs | 319 +++++++++++++ .../Integration/WorkflowTests.cs | 0 .../TestData/config-invalid-format.json | 32 ++ .../TestData/config-lenient-changes.json | 41 ++ .../TestData/config-malformed.json | 32 ++ .../TestData/config-namespace-filtering.json | 32 ++ .../config-strict-breaking-changes.json | 32 ++ 8 files changed, 915 insertions(+) create mode 100644 tests/DotNetApiDiff.Tests/Integration/CliWorkflowTests.cs create mode 100644 tests/DotNetApiDiff.Tests/Integration/ConfigurationWorkflowTests.cs create mode 100644 tests/DotNetApiDiff.Tests/Integration/WorkflowTests.cs create mode 100644 tests/DotNetApiDiff.Tests/TestData/config-invalid-format.json create mode 100644 tests/DotNetApiDiff.Tests/TestData/config-lenient-changes.json create mode 100644 tests/DotNetApiDiff.Tests/TestData/config-malformed.json create mode 100644 tests/DotNetApiDiff.Tests/TestData/config-namespace-filtering.json create mode 100644 tests/DotNetApiDiff.Tests/TestData/config-strict-breaking-changes.json diff --git a/tests/DotNetApiDiff.Tests/Integration/CliWorkflowTests.cs b/tests/DotNetApiDiff.Tests/Integration/CliWorkflowTests.cs new file mode 100644 index 0000000..471f487 --- /dev/null +++ b/tests/DotNetApiDiff.Tests/Integration/CliWorkflowTests.cs @@ -0,0 +1,427 @@ +// Copyright DotNet API Diff Project Contributors - SPDX Identifier: MIT +using System.Diagnostics;
