SWTBot Probe Scripts
Use this skill to create or update JSON probes for com.microsoft.copilot.eclipse.swtbot.test.
Probes drive the workbench through SWTBot actions and run as Tycho tests; no Java is compiled per test case.
Quick start
-
Create one focused JSON script at
com.microsoft.copilot.eclipse.swtbot.test/probe-scripts/<plan-slug>-<tc-id>.json.
-
Start by settling the workbench and opening the view under test:
[
{ "action": "waitForIdle" },
{ "action": "screenshot", "id": "01-startup" },
{ "action": "showView", "idRef": "com.microsoft.copilot.eclipse.ui.chat.ChatView" },
{ "action": "waitForIdle" },
{ "action": "screenshot", "id": "02-chat-open" }
]
-
Add user-level steps only, such as click, typeIn, clearElement, pressKey,
invokeCommand, waitFor, waitForMethod, assertExists, screenshot, or
dumpUi. Prefer widgetId locators for widgets the plugin owns.
-
Run from the repository root:
./mvnw clean verify -Dprobe.script=probe-scripts/<name>.json
Use root clean verify as the default. Tycho can reuse stale bundle jars
when only the SWTBot module is run, making source edits appear ignored. Use
xvfb-run -a on Linux headless.
-
Read com.microsoft.copilot.eclipse.swtbot.test/target/probe-results/results.json,
workspace.log, screenshots/, and ui-dumps/.
If -Dprobe.script is unset, ProbeRunner skips itself so ordinary ./mvnw verify runs are unaffected.
Authoring workflow
- Convert one scenario/test case into one probe. Split unrelated behaviors so each failure screenshot has one meaning.
- Drive the UI the way a user does.
invokeCommand is allowed for registered Eclipse command IDs; do not call
OSGi services, private methods, or test-only shortcuts.
- Pair screenshots with machine-checked assertions. Screenshots never fail a step;
assertExists, waitFor, and
waitForMethod decide pass/fail.
- Wait for asynchronous UI state before acting. For chat, wait for the
model-picker selected model before Send,
then wait for user-turn and model-info-label.
- When a locator fails, insert
dumpUi before the failure and inspect ui-dumps/*.xml for widget class names and
SWTBot widget IDs.
- For unauthenticated chat probes, assert the "Sign in to GitHub" UI. Do not poll internal auth managers.
Chat send skeleton
[
{ "action": "waitForIdle" },
{ "action": "showView", "idRef": "com.microsoft.copilot.eclipse.ui.chat.ChatView" },
{ "action": "waitFor", "locator": { "by": "styledText" }, "timeoutSec": 30 },
{ "action": "clearElement", "locator": { "by": "styledText" } },
{ "action": "typeIn", "locator": { "by":
Pass/fail judgment
A probe passes only when Maven exits 0 and results.json has "failed": 0.
On failure, inspect the failed step message, FAILED-stepNN-*.png, nearest ui-dumps/*.xml, and workspace.log.
Extending probes
The vocabulary lives in com.microsoft.copilot.eclipse.swtbot.test/src/.../probe/.
Add UI-level primitives in ProbeStep, Locator, and StepExecutor, then update REFERENCE.md.
See REFERENCE.md for action/locator tables, platform notes, result queries, troubleshooting, and current stable widget IDs.
