EDT-MCP — build and tests
Layout
- Maven/Tycho reactor:
mcp/ (bom, bundles, features, repositories, targets, tests).
- Unit tests:
mcp/tests/com.ditrix.edt.mcp.server.tests/src (JUnit4, a plug-in fragment).
- E2E:
tests/e2e/run_all.py + tools/test_<tool>.py (Python; runs the MCP server against TestConfiguration/).
Build
A Tycho build from mcp/ (Maven, JDK 17). The artifact is a p2 update-site in repositories/com.ditrix.edt.mcp.server.repository/target.
A local build is available — use it to validate Java edits (don't claim "verified by review/grep only"). The canonical script is source/compile.sh (it reproduces the CI flow mvn clean verify -T 1C from .github/workflows/build.yml):
bash source/compile.sh
bash source/compile.sh --skip-tests
- The toolchain (JDK 17 + Maven 3.9+) is often not on
PATH — pass it explicitly: --java-home <JDK17 home> --maven-home <maven home> (or env JAVA_HOME/MAVEN_HOME). The exact paths are machine-specific — discover them on the spot, don't hardcode into committed files. Exact options are in README "Building from source".
- The first build is slow: Tycho pulls the EDT p2 repository (
edt.1c.ru) + the Eclipse SDK (hundreds of MB). Once the caches are warm (~/.m2/repository/p2, .cache/tycho) it runs in ~1 minute. If the caches are absent and there's no network, the build legitimately can't run — say so, don't fake "green".
- Unit tests need the target platform too (Mockito/JUnit come from the p2 target, not plain Maven Central) — a green
compile.sh is the real proof for Java edits; grep only catches anchor/text problems.
Unit tests — conventions
- One
XxxToolTest per tool (tools/impl/), JUnit4.
- Base pattern:
tool.execute(params) + a sentinel-message check (e.g. "Project not found") for argument validation. Reference: WriteModuleSourceToolTest.
- Bilingual invariant: for tools that resolve metadata/code, a case with a Russian identifier/synonym (reference
WriteModuleSourceToolTest.testResolveRussianObjectName). See skill edt-mcp-bilingual.
Coverage gate
BuiltInToolTestCoverageTest (unit) fails the build if a registered tool has no XxxToolTest; the e2e coverage ratchet (tools/test_coverage_ratchet.py) fails the suite if a tools/list tool has no test_<tool>.py. Adding a tool without a test fails the build.
E2E
tests/e2e/run_all.py (+ tools/test_<tool>.py, one per tool) runs scenarios against the live server and TestConfiguration/ with git-fixture isolation. The round-trip of Cyrillic synonyms and the synonym-keyed-by-language-code check live in test_create_metadata.py / test_get_metadata_details.py. A new tool — add tools/test_<tool>.py. Full guide: edt-mcp-e2e-testing (and tests/e2e/SKILL.md).
Protocol conformance
A separate gate from the e2e business-logic suite: the official modelcontextprotocol/conformance suite validates the SERVER against the MCP wire spec (handshake, capabilities, session-id, isError, ping, SSE). Lives in tests/conformance/ (baseline.yml pins the intentional gaps; README.md explains the layer split). Run: npx @modelcontextprotocol/conformance@latest server --url http://127.0.0.1:8765/mcp --spec-version 2025-11-25 --expected-failures tests/conformance/baseline.yml.
