junit-workshop's Introduction

Unit

  1. Unit-тесты:
  • быстрый запуск и устранение ошибок;
  • уверенность: проверка всех деталей алгоритмов;
  • рефакторинг: удаление избыточного и грязного кода.
  1. Фреймворки
  2. Базовые фреймворки Unit-тестирования: * JUnit; * TestNG;
  3. Hamcrest;
  4. Mock-тестирование: * Mockito; * PowerMock; * Easymock; * JMockit;
  5. Собственный набор утилит: test-util * TestUtil:
    • uid(), newDate(), уникальные значения для тестов;
    • toDate(Date), format(Date, format), parse(str, parsePatterns), toCalendar(Date), преобразование даты/времени;
    • dec(String), dec(double), преобразования в BigDecimal;
    • readFileToString(testClass, suffix, encoding), getFile; * Rules:
    • MockitoRule, verifyInOrder;
    • BeforeMockRule, инициализация до Mockito;
    • LoggerRule, тестирование логов;
    • ParameterizedRule, параметризация тестов;
    • TempDirRule, временные файлы теста;
    • JpaRule, тестирование JPA 2.0;
  6. Примеры:
  • test-00, пустой проект;
  • test-01, JUnit, assertEquals, SimpleDateFormat.parse, TestUtil.toDate;
  • test-02, Hamcrest, Mockito, assertThat, MockUtils.verifyInOrder, Captor, self, PropertiesMatcher, рефакторинг, PowerMock;
  • test-04, наследование, TestUtil.readFileToString;
  • test-05, параметризированные тесты, TestUtil.uid(Enum.class);
  • test-03, полное тестирование legacy-кода, answer, рефакторинг, безопасное закрытие ресурсов.
