基本單元測試示例

此示例是使用 junit 對 StringBuilder.toString() 進行單元測試的基本設定。

import static org.junit.Assert.assertEquals;

import org.junit.Test;

public class StringBuilderTest {

    @Test
    public void stringBuilderAppendShouldConcatinate()  {
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append("String");
        stringBuilder.append("Builder");
        stringBuilder.append("Test");

        assertEquals("StringBuilderTest", stringBuilder.toString());
    }

}
