Re-using step definitions not working (always undefined)
I'm trying to re-use the steps but when I try to log the myAccount variable on the test function it's always undefined, and passing it forward as argument it gives me errors saying I can't call methods from undefined. (https://github.com/bencompton/jest-cucumber/blob/master/docs/ReusingStepDefinitions.md)
The easiest way to see this problem is to console.log(myAccount) here: https://github.com/bencompton/jest-cucumber/blob/1a9ef75f5602d5b18dd4b33d08130e878799da59/examples/typescript/specs/step-definitions/using-dynamic-values.steps.ts#L14
How can I solve this? Thank you.
Hi @zefexdeveloper I figured out the solution to use shared steps. You can use callback to send account to shared steps.
Example:
// shared-steps.js
export const givenIHaveXDollarsInMyBankAccount = (given, accountCallback) => {
given(/I have \$(\d+) in my bank account/, balance => {
accountCallback().deposit(balance);
});
};
export const thenMyBalanceShouldBe = (then, accountCallback) => {
then(/my balance should be \$(\d+)/, balance => {
expect(accountCallback().balance).toBe(parseInt(balance));
});
};
// example.steps.js
import { thenMyBalanceShouldBe, givenIHaveXDollarsInMyBankAccount } from './shared-steps';
defineFeature(feature, test => {
let myAccount;
beforeEach(() => {
myAccount = new BankAccount();
});
test('Making a deposit', ({ given, when, then }) => {
givenIHaveXDollarsInMyBankAccount(given, () => myAccount);
when(/I deposit \$(\d+)/, deposit => {
myAccount.deposit(deposit);
});
thenMyBalanceShouldBe(then, () => myAccount);
});
test('Making a withdrawal', ({ given, when, then }) => {
givenIHaveXDollarsInMyBankAccount(given, () => myAccount);
when(/I withdraw \$(\d+)/, withdrawal => {
myAccount.withdraw(withdrawal);
});
thenMyBalanceShouldBe(then, () => myAccount);
});
});
