用JUnit4進行單元測試程式碼編寫
阿新 • • 發佈:2019-01-02
JUnit4簡介
Junit是一個可編寫重複測試的簡單框架,是基於Xunit架構的單元測試框架的例項。JUnit4是JUnit框架有史以來的最大改進,其主要目標便是利用JDK 5的Annotation特性簡化測試用例的編寫。JDK 5裡可以靜態匯入,例如import static org.junit.Assert.*;。Annotation又稱註解(或元資料),其實就是@Before、@After、@BeforeClass、@AfterClass、@Test等等。
@Before @BeforeClass @After @AfterClass的區別
簡單來說,@[email protected]
而@[email protected]從頭至尾僅會執行一次。對於那些較耗資源的,建議採用這種方法。
當然二者還有很多其他區別,詳見部落格:

@Test執行順序
一般來說,被@Test註解的方法是隨機順序執行的,因為單元測試,本身它們就應該是互不干擾可以獨立執行的。
但是某些特殊情況下,想讓它按照一定順序執行的話,可以使用@FixMethodOrder(MethodSorters.NAME_ASCENDING),放在JUnit測試類定義的外面,這樣一來就會按照方法名稱的升序來執行。此時命好方法的名字,就可以輕鬆實現既定順序執行。

將JUnit4測試類放在被測類的同一package下,讓它們處於同一層級,這樣就不用import被測類了。

public void test5_select() throws InterruptedException {

assertEquals(true,afterSelect.getPageSource().contains("以下是查詢到的使用者列表(最多顯示 100 個)"));
}
}
