- 3. Docker & Microservices Docker Is one of the Reason to make the microservices popular, that helps the software to build and ship faster. user details -mysql Flight Details Service Reservation Service flightdetails - mysql Reservation- mysql User login Service 7070 9090 6060 Docker Containers
- 4. Swagger ● A Good Friend of Qa. ● Rest Api Documentation Api ● Many other Features http://localhost:7070/userdetails/swagger-ui.html http://localhost:6060/reservation/swagger-ui.html http://localhost:9090/flightdetails/swagger-ui.html .
- 5. Unit Tests UNIT TESTING is a level of software testing where individual units/ components of a software are tested. A unit is the smallest testable part of any software, for eg, a class method.
- 6. On which side of the pyramid should the following validations test lie: ● Passenger.cardNumber.length = 16 ● Passenger.firstName.length > 3 ● Passenger.lastName.length > 3 ● Passenger.phoneNumber.length > 3 ● Passenger.phoneNumber contains only numerals ● Passenger.flightId != null ● Passenger.email contains @
- 7. ● A unit or a method may exhibit multiple behaviors and hence, each behavior must be tested as a separate test and not all in one. ● Always use mocks for simulating external behavior when testing a method or a unit in isolation. Best Practices of writing Unit Tests
- 8. @Test public void validateReservationData() { Passenger passenger = new Passenger(); passenger.setFirstName("some invalid name"); passenger.setLastName("some invalid name"); passenger.setPhone("some invalid name"); passenger.setEmail("some invalid name"); reservation.setFlight_id(null); reservation.setPassenger(passenger); assertTrue("first name is invalid",ReservationValidator .isValidPassengerName(reservation.getPassenger().getFirstName())); assertTrue("last name is invalid",ReservationValidator .isValidPassengerName(reservation.getPassenger().getLastName())); assertTrue("email is invalid",ReservationValidator .isValidPassengerName(reservation.getPassenger().getEmail())); assertTrue("phone is invalid",ReservationValidator .isValidPassengerName(reservation.getPassenger().getPhone())); } Bad Practice
- 9. @Test public void validatePassengerEmail() { } @Test public void validatePassengerContact() { } @Test public void validateFlightId) { } @Test public void validatePassengerEmail() { } Good Practice

- 21. Monitoring ● We need to monitor the Services As part of Testing. ● Services should be configured in such a way that an alarm is raised in case of a failure.
