I want to execute a hook for every describe call. My structure should look like this:
describe('Main', ()=> {
beforeEach(() => {
// should call for every describe
})
describe('Sub', () => {
it('some tests', ()=> {
})
it('some tests2', ()=> {
})
})
describe('Sub 2', () => {
it('some tests', ()=> {
})
})
})I tried executing this but beforeEach fires for every test not every describe.
You can patch the standard describe() function, which will add the hook transparently.
const originalDescribe = global.describe
const describe = (title, callback) => {
originalDescribe(title, () => {
before(() => {
console.log('describe', title)
});
callback();
});
}
describe('Main', ()=> {
describe('Sub', () => {
it('some tests', ()=> {
console.log('it', 1)
})
it('some tests2', ()=> {
console.log('it', 2)
})
})
describe('Sub 2', () => {
it('some tests', ()=> {
console.log('it', 3)
})
})
})
Or another (simpler) approach is just to call you beforeDescribe() hook at the start of each describe() block.
const beforeDescribeHook = () => {
const title = Cypress.mocha.getRunner().suite.title;
console.log('describe', title)
}
describe('Main', ()=> {
before(beforeDescribeHook)
describe('Sub', () => {
before(beforeDescribeHook)
it('some tests', ()=> {
console.log('it', 1)
})
it('some tests2', ()=> {
console.log('it', 2)
})
})
describe('Sub 2', () => {
before(beforeDescribeHook)
it('some tests', ()=> {
console.log('it', 3)
})
})
})
Since beforeEach() won't execute before each describe block, you have to create a custom function to achieve this. You can do something like this. Create a custom function and instead of describe block you can call this function to run the before block every time.
function customSuite(name, tests) {
describe(name, function() {
before(function() {
//Do Something
});
tests();
});
}
describe('Main', () => {
customSuite('Sub1', function() {
it('some tests', function() {
})
it('some tests2', function() {
})
})
customSuite('Sub2', function() {
it('some tests', function() {
})
})
})
I had the same problem and found the workaround of just putting one testcase inside of the highest describe like this:
describe( () => {
beforeEach(//do smth)
it('workaround', () => {})
describe( () => {
//executes beforeEach here
})
describe( () => {
//executes beforeEach here also
})
})
As you can see the test can be comletely empty. But maybe you will even find some use for it. Let me know if it also worked for you!
