# Testes Além do Código

Projeto utilizado na apresentação da palestra "Testes Além Do Código" na trilha Testes no TDC Connections 2022.

## Sobre o Projeto

O projeto consiste em uma pequena calculadora contendo as quatro operações básicas: `soma`, `subtração`, `multiplicação` e `divisão`.

### Exemplo de teste tradicionalmente escrito:

```java

@Test

void shouldBeApplySum() {

    OperationData operationData = OperationData.builder()

        .firstNumber(10)

        .secondNumber(10)

        .build();

    BigDecimal actual = SUM.execute(operationData);

    Assertions.assertThat(actual)

        .usingComparator(BigDecimal::compareTo)

        .isEqualTo(BigDecimal.valueOf(20));

}

```

### Exemplo de teste utilizando DSL + Method Chaining:

```java

@Test

void shouldBeApplySumWithDsl() {

    given()

        .firstNumberEqualTo(10)

        .secondNumberEqualTo(10)

    .when(SUM::execute)

    .then()

        .assertResult()

            .isEqualTo(20);

}

```

### Exemplo com cenário de falha utilizando DSL + Method Chaining:

```java

@Test

void shouldBeThrownBusinessExceptionWhenApplyingDivisionByZero() {

    given()

        .firstNumberEqualTo(10)

        .secondNumberEqualTo(0)

    .when(DIVISION::execute)

    .then()

        .assertException()

            .isInstanceOf(BusinessException.class)

            .messageIsEqualTo("An unexpected error occurred");

}

```
