Test Fixtures & Interface Adaptors
We offer reliable test fixture solutions to meet your requirements. A test fixture kit is essential for setting up consistent testing conditions.
Overview
A Test Fixture is a dedicated hardware environment used to consistently test some item, device, or piece of software. Test fixtures can be found when testing electronics, software and physical devices. A complete test fixture kit is often required for thorough testing.
In testing electronic equipment such as circuit boards, electronic components, and chips, a test fixture is a device or setup designed to hold the device under test (DUT) in place and allow it to be tested by being subjected to controlled electronic test signals.
Test signals are applied using gold-plated, spring-loaded test probes sometimes referred to as a ‘bed of nails’ testing method. A comprehensive test fixture kit includes these essential components.
Advantages
The advantage of a test fixture is that it allows for tests to be repeatable for greater integrity since each test is always starting with the same setup. Test fixtures also ease test code design by allowing the developer to separate methods into different functions and reuse each function for other tests. Further, test fixtures per-configure tests into a known initial state instead of working with whatever was left from a previous test run. A disadvantage is that it could lead to duplication of test fixtures if using in-line setup. Nevertheless, investing in a test fixture kit can mitigate some of these challenges.
