From 6cf0aac96ae0abb455ee8525e0ede9a63f5974f3 Mon Sep 17 00:00:00 2001 From: Craig Jennings Date: Tue, 4 Nov 2025 07:56:31 -0600 Subject: Add comprehensive ERT test suite and fix critical bugs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Session 1: Testing infrastructure and initial test coverage Bug fixes in wttrin.el: - Fix wttrin-additional-url-params to handle nil unit system - Remove incorrect callback parameter to url-retrieve-synchronously - Add nil buffer check for network failures - Strip HTTP headers before decoding response - Kill buffer after fetch to prevent memory leaks - Fix double concatenation of URL params in cache function - Add proper URL encoding via new wttrin--build-url function Refactoring: - Extract wttrin--build-url as pure, testable function - Separate URL building logic from network I/O Test infrastructure (33 tests, 100% passing): - tests/testutil-wttrin.el: Shared test utilities - tests/test-wttrin-additional-url-params.el: 7 tests - tests/test-wttrin--make-cache-key.el: 9 tests - tests/test-wttrin--build-url.el: 10 tests - tests/test-wttrin--cleanup-cache-if-needed.el: 7 tests Documentation: - docs/testing-plan.org: Comprehensive testing roadmap - docs/bugs.org: Bug analysis from code review - docs/NOTES.org: Session tracking and guidelines - docs/session-1-summary.org: Detailed session summary Next session: Cache workflow tests, parsing logic extraction, integration tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/test-wttrin--cleanup-cache-if-needed.el | 124 ++++++++++++++++++++++++++ 1 file changed, 124 insertions(+) create mode 100644 tests/test-wttrin--cleanup-cache-if-needed.el (limited to 'tests/test-wttrin--cleanup-cache-if-needed.el') diff --git a/tests/test-wttrin--cleanup-cache-if-needed.el b/tests/test-wttrin--cleanup-cache-if-needed.el new file mode 100644 index 0000000..c280723 --- /dev/null +++ b/tests/test-wttrin--cleanup-cache-if-needed.el @@ -0,0 +1,124 @@ +;;;
