What it does
Swing UI Test Headless Guard is an agent skill from lakernote/easy-postman. Use when adding or updating EasyPostman Swing/TestNG UI tests that may run in headless CI or no-display Linux environments.
Its SKILL.md is about 280 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering API testing. It works with Linux, Postman and Java. The repository describes itself as: An open-source API debugging and stress testing tool inspired by Postman and a simplified JMeter, optimized for developers with a clean UI and powerful features. The licence is Apache-2.0.
When your agent uses it
- Updating EasyPostman Swing/TestNG UI tests that may run in headless CI
- No-display Linux environments
Example prompts
- “/swing-ui-test-headless-guard”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Put shared no-display skip logic in
- Make Swing/UI tests extend that base class.
- Use @BeforeClass + SkipException to skip tests when
What it can do on your machine
Read from SKILL.md and the folder at commit 3d6ccbc. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
mvn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Swing UI Test Headless Guard loads about 275 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 103 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Swing UI Test Headless Guard
Use this skill for Swing UI tests under easy-postman-app/src/test/java.
Default pattern
- Put shared no-display skip logic in:
easy-postman-app/src/test/java/com/laker/postman/test/AbstractSwingUiTest.java - Make Swing/UI tests extend that base class.
- Use
@BeforeClass+SkipExceptionto skip tests when:GraphicsEnvironment.isHeadless()istrue- or Linux has neither
DISPLAYnorWAYLAND_DISPLAY
Guardrails
- Keep the base class narrow. Only put environment-skip behavior there unless multiple UI tests clearly need more.
- Do not add this base class to non-UI tests.
- Prefer
SkipExceptionover brittle per-test conditionals. - After changes, verify with:
mvn -q -pl easy-postman-app -am -DskipTests compilemvn -q -pl easy-postman-app -am -Dtest=<TestClass> -Dsurefire.failIfNoSpecifiedTests=false -Djava.awt.headless=true test
