From bcbaf4a6781d6e67c3a644115853b03809302c90 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Wed, 16 Jul 2025 11:39:53 -0700 Subject: [PATCH] **test(tests): enhance test clarity, isolation, and robustness** - **Test Improvements**: - Introduced data-clearing steps (`.clear()`) across critical test cases for ensuring better test isolation and preventing state leakage. - Extended support for overriding global utilities (`testUtils`) and added fallback behaviors for test vector creation. - **Configuration Updates**: - Added support for `distanceFunction` as an alternative to `metric` in vector operations for consistency. - Adjusted and unified asynchronous `timeout` handling across test suites for predictability. - **Purpose**: - These updates improve reliability, maintainability, and clarity in test cases while ensuring compatibility across diverse test environments. --- tests/core.test.ts | 97 +++++++++++++++++++------------ tests/environment.browser.test.ts | 58 ++++++++++++------ tests/environment.node.test.ts | 58 +++++++++++------- tests/setup.ts | 21 ++++--- tests/vector-operations.test.ts | 62 +++++++------------- 5 files changed, 170 insertions(+), 126 deletions(-) diff --git a/tests/core.test.ts b/tests/core.test.ts index 3ccaaea7..bfa90804 100644 --- a/tests/core.test.ts +++ b/tests/core.test.ts @@ -97,6 +97,7 @@ describe('Brainy Core Functionality', () => { }) await data.init() + await data.clear() // Clear any existing data // Add vectors await data.add([1, 0, 0], { id: 'v1', label: 'x-axis' }) @@ -118,6 +119,7 @@ describe('Brainy Core Functionality', () => { }) await data.init() + await data.clear() // Clear any existing data // Add multiple vectors const vectors = [ @@ -148,6 +150,10 @@ describe('Brainy Core Functionality', () => { await euclideanData.init() await cosineData.init() + + // Clear any existing data to ensure test isolation + await euclideanData.clear() + await cosineData.clear() const vector = [1, 1] const metadata = { id: 'test' } @@ -168,51 +174,61 @@ describe('Brainy Core Functionality', () => { }) describe('Text Processing', () => { -
