From 83b241ae809d46d24e4ebc8ecf5c385da62b05de Mon Sep 17 00:00:00 2001 From: "Matt Godbolt (bot acct)" Date: Wed, 18 Feb 2026 20:39:27 -0600 Subject: [PATCH] feat(cypress): executor, GCC dump, preprocessor, opt remarks, and shortcut tests (#8489) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary 14 new Cypress E2E tests across 5 new spec files, plus shared helpers extracted to utils.ts. ### New test files | File | Tests | What it covers | |------|-------|----------------| | `execute.cy.ts` | 4 | Executor pane: open, stdout, stderr, non-zero exit codes | | `gccdump.cy.ts` | 3 | GCC Tree/RTL dump: open, pass picker, dump content | | `pp-view.cy.ts` | 4 | Preprocessor: open, `#define` expansion, `#include` macro expansion, source change updates | | `opt-view.cy.ts` | 2 | Optimisation remarks: open, shows remarks with `-O2` | | `shortcuts.cy.ts` | 1 | Ctrl+Enter triggers recompilation | ### Shared helpers added to utils.ts - `openPaneFromCompiler(buttonId)` — generic helper for any compiler toolbar pane button - `openExecutor()`, `openGccDump()`, `openPreprocessor()`, `openOptRemarks()` — convenience wrappers ### Result - Total test count: 82 (68 existing + 14 new) - All passing locally and should pass on CI (uses only `gdefault`) *(I'm Molty, an AI assistant acting on behalf of @mattgodbolt)* 🤖 Generated by LLM (Claude, via OpenClaw) --------- Co-authored-by: mattgodbolt-molty --- cypress/e2e/execute.cy.ts | 83 ++++++++++++++++++++++++++++++++++ cypress/e2e/gccdump.cy.ts | 67 ++++++++++++++++++++++++++++ cypress/e2e/opt-view.cy.ts | 49 +++++++++++++++++++++ cypress/e2e/pp-view.cy.ts | 88 +++++++++++++++++++++++++++++++++++++ cypress/e2e/shortcuts.cy.ts | 74 +++++++++++++++++++++++++++++++ cypress/support/utils.ts | 30 +++++++++++++ 6 files changed, 391 insertions(+) create mode 100644 cypress/e2e/execute.cy.ts create mode 100644 cypress/e2e/gccdump.cy.ts create mode 100644 cypress/e2e/opt-view.cy.ts create mode 100644 cypress/e2e/pp-view.cy.ts create mode 100644 cypress/e2e/shortcuts.cy.ts diff --git a/cypress/e2e/execute.cy.ts b/cypress/e2e/execute.cy.ts new file mode 100644 index 000000000..9616f3a5e --- /dev/null +++ b/cypress/e2e/execute.cy.ts @@ -0,0 +1,83 @@ +// Copyright (c) 2026, Compiler Explorer Authors +// All rights reserved. +// +// Redistribution and use in source and binary forms, with or without +// modification, are permitted provided that the following conditions are met: +// +// * Redistributions of source code must retain the above copyright notice, +// this list of conditions and the following disclaimer. +// * Redistributions in binary form must reproduce the above copyright +// notice, this list of conditions and the following disclaimer in the +// documentation and/or other materials provided with the distribution. +// +// THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" +// AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE +// IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE +// ARE DISCLAIMED.
