Gdunit4 Test Writer

gdUnit4 Test Writer

Write gdUnit4 test code for GDScript files with proper assertions and test structure.

Workflow

1. Analyze target file - Read the GDScript file to understand what needs testing
2. Check gdUnit4 docs - Use Context7 (/websites/godot-gdunit-labs_github_io_gdunit4) if needed
3. Select assertions - Use type-specific assertions (see [references/assertions.md])
4. Create test file - Place in res://tests/ directory with test_*.gd naming (e.g., test_player.gd)

Quick Reference

Test File Template

extends GdUnitTestSuite

func test_example() -> void:
    assert_int(1).is_equal(1)

Common Assertions

• int: assert_int(value).is_equal(10)
• float: assert_float(value).is_equal_approx(3.14, 0.01)
• String: assert_str(text).contains("hello")
• Array: assert_array(items).has_size(5)
• Object: assert_object(node).is_not_null()
• Signal: await assert_signal(emitter).is_emitted("signal_name")

Memory Management

func test_with_node() -> void:
    var node: Node = auto_free(Node.new())  # Auto-freed after test
    assert_object(node).is_not_null()
