From 440e31a7b609aa9c149bcd125f7e789cb310835d Mon Sep 17 00:00:00 2001 From: "github-actions[bot]" <41898282+github-actions[bot]@users.noreply.github.com> Date: Mon, 6 Jul 2026 17:36:36 +0000 Subject: [PATCH] test: Add @WebMvcTest tests for ProjectController (16 tests, 2 bug pins) - Tests for all 8 endpoints: GET /api/projects, GET /{id}, GET /code/{code}, POST, PUT /{id}, DELETE /{id}, GET /{id}/dashboard, POST /{id}/members - Bug-pin: POST /api/projects returns 200 instead of 201 Created - Bug-pin: GET /{id}/dashboard with taskCount=0 returns NaN in JSON body (Project.getProgress() returns NaN, which Jackson serializes as the literal token 'NaN' - not valid JSON) - Documents getMemberIds() NPE when members is null (test data sets members to avoid triggering separate bug during serialization) Tests run: 54 (+16), Failures: 1, Errors: 1, Skipped: 7 Pre-existing failures unchanged (DateUtilsTest#6, TaskServiceTest#3) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../controller/ProjectControllerTest.java | 288 ++++++++++++++++++ 1 file changed, 288 insertions(+) create mode 100644 src/test/java/com/taskflow/controller/ProjectControllerTest.java diff --git a/src/test/java/com/taskflow/controller/ProjectControllerTest.java b/src/test/java/com/taskflow/controller/ProjectControllerTest.java new file mode 100644 index 0000000..35cc9e0 --- /dev/null +++ b/src/test/java/com/taskflow/controller/ProjectControllerTest.java @@ -0,0 +1,288 @@ +package com.taskflow.controller;
