Function to run before each test (can be sync or async)
describe('CAN Communication Tests', () => {
// ✅ Correct: beforeEach inside describe block
beforeEach(async () => {
await can.open('kvaser', 0);
await can.setBitrate(500000);
});
beforeEach(() => {
uds.setTesterPresent(true);
uds.setTimeout(5000);
});
test('should send CAN message', () => {
// Test implementation
});
});
// ❌ Wrong: beforeEach outside describe block
// beforeEach(() => { // This will not work properly });
Run setup code before each test in the current suite. MUST be used within a describe block. Only executes if the corresponding test is enabled through testEnableControl. Useful for initializing test data, establishing connections, or setting up mock objects.
