QA fixtures

Small, realistic projects for manual QA and end-to-end tests of OpenIDEA. Each one has a few source files, passing tests, an opt-in failing test, TODO/FIXME comments and at least one intentional warning, so every IDE feature has something to show.

Fixture	Toolchain	Run	Tests	Failing test	Intentional warning

The fixtures are standalone: rust-app declares its own [workspace] and fixtures/eslint.config.js keeps them out of the IDE's own lint run.

The language smoke test (crates/ide-host/tests/language_smoke.rs) runs completion, navigation, diagnostics, quick fixes, formatting and rename on these projects with real language servers, smoke/run.test.ts runs each project's run and test configurations (the intentionally failing test included, then Rerun Failed Tests), and smoke/debug.test.ts debugs its entry point from the "Set a breakpoint here" line: when you change a fixture, run them for that language.

Setup

Work on a copy so git and edits never touch this repository:

cp -R fixtures/rust-app /tmp/qa-rust && cd /tmp/qa-rust
git init -q && git add -A && git commit -qm "initial"   # for the VCS checks

Then open the folder with File › Open… (⌘⇧⌥O) or from the Welcome screen. For ts-app / polyglot/web run pnpm install first; for python-app create a venv (python3 -m venv .venv && .venv/bin/pip install -e '.[dev]'); for php-app run composer install (debugging it needs Xdebug in the PHP on PATH).

Missing language servers / debuggers can be installed from the IDE: Settings › Languages & Frameworks › Language Servers, or from the "… is not installed — Install" notification shown when a file is opened.

QA checklist

Run each block on at least rust-app and one other fixture; tick polyglot for language detection and highlighting.

Open & workbench

• Opening the folder shows the project name in the title bar, the Project tool window (⌘1) on the left, stripes on both sides and the status bar.
• Indexing progress appears in the status bar and finishes.
• Closing and reopening the window restores open tabs and tool windows.

Project tree

• Arrow keys move the selection; →/← expand/collapse; Enter/F4 opens a file.
• Ignored folders (target/, node_modules/, build/, vendor/) appear dimmed.
• New file (⌘N), rename (⇧F6), delete (⌫) work and the tree updates.

Search Everywhere & navigation

• Double ⇧ opens Search Everywhere; typing parser finds src/parser.rs.
• ⌘O (classes) finds Inventory / Cart / TaskList / Library / Shipment.
• ⌘⇧O (files) and ⌘⌥O (symbols) find format_price / formatMoney.
• ⌘E lists recent files; ⌘[ / ⌘] navigate back/forward.
• ⌘B on a call (format_price in main.rs, cart.total() in index.ts, billableGrams in quote.php) jumps to the declaration; ⌥F7 lists usages.
• ⌘F12 shows the file structure; ⌘L goes to a line.

Editing & code insight

• Typing in a file marks the tab modified; ⌘S saves; external edits reload.
• ⌘F opens the find bar (match case / words / regex); ⌘R replaces.
• ⌘⇧F finds TODO across the project and opens results.
• Completion (⌃Space) on inventory. / cart. / tasks. / $parcel-> lists members.
• Hover / F1 shows documentation; ⌘P shows parameter info.
• Warnings: the intentional warning is underlined and listed in Problems (⌘6); F2 jumps to it; ⌥Enter offers a quick fix.
• Rename (⇧F6) total_value / subtotal / pending updates every usage (check the preview) and undo restores them.
• Reformat (⌘⌥L), comment line (⌘/), duplicate line (⌘D) and extend selection (⌥↑) behave like IDEA.

TODO

• The TODO tool window lists every TODO/FIXME in the fixture and opens them.

Run configurations & tests

• Run configurations are detected: cargo run/test (Rust), package.json scripts (TS), pytest (Python), go test / go run (Go), Gradle tasks (Kotlin), composer.json scripts and Pest (PHP).
• Gutter run icons appear next to main and test functions; running one opens the Run tool window (⌘4) with the output.
• The test tree shows passed tests; enabling the failing test (table above) shows it red with the assertion message and a link to the source line.
• ⌘F2 stops a running process (try go run ./cmd/server).

Debugger

• Each fixture's entry point has a "Set a breakpoint here" comment: toggle a breakpoint there (⌘F8) and start debugging (⌃D).
• Execution stops on the line; Frames and Variables show inventory / cart / tasks / library / $shipment; inline values appear in the editor.
• Step over (F8), into (F7), out (⇧F8), resume (⌘⌥R) and evaluate (⌥F8).
• If the debug adapter is missing (CodeLLDB, debugpy, Delve, PHP Debug), the error offers the installer and debugging works after installing.

Git

• Edited lines show gutter change markers; the tree and tabs colour modified files.
• Commit tool window (⌘0 / ⌘K) lists changes with a diff; partial staging works.
• Committing clears the changes; Git log (⌘9) shows the commit; blame works.
• Creating and switching branches from the status bar widget works.

Terminal

• ⌥F12 opens the terminal in the project root; run the test command there.
• Several tabs, resize, copy/paste and exit behave; the shell's PATH includes tools installed by the IDE.

Settings & installer

• ⌘, opens Settings; search finds "Language Servers".
• Language Servers lists each tool with languages, status (Installed / On PATH / Missing) and version; Install streams progress and can be cancelled; Uninstall removes managed tools. Nothing downloads without clicking Install.
