在一個Java文件中初始化值，測試套件的所有其他junit類從該Java文件中獲取數據

Question

我想使用JUnit創建一個測試套件，其中一個Java類初始化值，而所有其他JUnit測試類從該類獲取它們的值。

我創建了一個BaseTestclass.java類，其中已經初始化了Stock.java類的值，並且我正在使用JUnit測試類TestClass1 ，其中我想使用由BaseTestClass.java初始化的BaseTestClass.java 。 我正在使用測試套件AllClass.java來運行兩個類。

Stock.java：

package com.practiseEasyMock.EasyMockPractise;

public class Stock {
  private String stockId;
  private String name;
  private Integer quantity;
  public String getStockId() {
    return this.stockId;
  }
  public void setStockId(final String stockId) {
    this.stockId = stockId;
  }
  public String getName() {
    return this.name;
  }
  public void setName(final String name) {
    this.name = name;
  }
  public Integer getQuantity() {
    return this.quantity;
  }
  public void setQuantity(final Integer quantity) {
    this.quantity = quantity;
  }
}

BaseTestClass.java：

package com.practiseEasyMock.EasyMockPractise;

import java.util.ArrayList;
import java.util.List;

public class BaseTestClass {
  private Stock googleStock, microsoftStock;
  private List<Stock> stocks;
  public void setCommonString() {
    this.googleStock = new Stock();
    this.googleStock.setName("Google");
    this.microsoftStock = new Stock();
    this.microsoftStock.setName("Microsoft");
    this.stocks = new ArrayList<Stock>();
    this.stocks.add(this.googleStock);
    this.stocks.add(this.microsoftStock);
  }
  public Stock getGoogleStock() {
    return this.googleStock;
  }
  public Stock getMicrosoftStock() {
    return this.microsoftStock;
  }
  public List<Stock> getStocks() {
    return this.stocks;
  }
}

TestClass1.java：

package com.practiseEasyMock.EasyMockPractise;

import org.easymock.EasyMockRunner;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(EasyMockRunner.class)
public class TestClass1 {
  private BaseTestClass baseTestClass;
  @Test
  public void testSuite1MarketValue() {
    this.baseTestClass = new BaseTestClass();
    this.baseTestClass.setCommonString();
    Assert.assertEquals("Google", this.baseTestClass.getGoogleStock().getName());
    Assert.assertEquals("Microsoft", this.baseTestClass.getMicrosoftStock().getName());
  }
}

測試套件：AllTests.java

package com.practiseEasyMock.EasyMockPractise;
import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

@RunWith(Suite.class)
@SuiteClasses({BaseTestClass.class, TestSuite1.class})
public class AllTests {
}

因此，現在當我運行測試套件時，出現以下錯誤：

請幫忙...

Answer 1

BaseTestClass不包含任何測試。 這就是錯誤“無可運行方法”的原因。 從BaseTestClass的@SuiteClasses批注中刪除BaseTestClass 。
