java - 有两种方法的 jUnit 失败

Question

我有一个测试类，其中有两个注释为 @Test 的方法。

如果我通过注释另一个方法来单独运行每个方法，它就会成功。但如果两者一起运行，就会失败。可能是什么原因？

public class ProductAvailTest {
private static final String PRODUCT_AVAIL_BUILDER = "ProductAvailBuilder";


@Test
public void productAvailResponseDateRequired() throws Exception {

    ResponseBuilderFactory responseBuilderFactory = ResponseBuilderFactory.createResponseBuilderFactory();
    ResponseBuilder responseBuilder = responseBuilderFactory.createResponseBuilder(PRODUCT_AVAIL_BUILDER);
    ProductAvailDateRqdHelper productAvailDateRqdHelper = new ProductAvailDateRqdHelper();
    List<Rsproducts> products = productAvailDateRqdHelper.getLOMProducts();

    // TODO change this to logger
    System.out.println("No. of products in test " + products.size());

    GetProductAvailOutput actualProductAvailOutput = (GetProductAvailOutput) responseBuilder.buildSuccessResponse(
            products, productAvailDateRqdHelper.getProductAvailInput());
    GetProductAvailOutput expectedProductAvailOutput = productAvailDateRqdHelper.getProductAvailOutput();

    // TODO change this to logger
    System.out.println("Size in expected " + expectedProductAvailOutput.getProductBrand().size());
    System.out.println("Size in actual " + actualProductAvailOutput.getProductBrand().size());

    Assert.assertEquals(expectedProductAvailOutput, actualProductAvailOutput);

}


@Test
public void productAvailResponseInvBased() throws Exception {
    ResponseBuilderFactory responseBuilderFactory = ResponseBuilderFactory.createResponseBuilderFactory();
    ResponseBuilder responseBuilder = responseBuilderFactory.createResponseBuilder(PRODUCT_AVAIL_BUILDER);
    ProductAvailInvHelper productAvailInvHelper = new ProductAvailInvHelper();
    List<Rsproducts> products = productAvailInvHelper.getLOMProducts();

    // TODO change this to logger
    System.out.println("No. of products in test " + products.size());

    System.out.println("No of inventory " + products.get(0).getRsproddtls().size());


    GetProductAvailOutput actualProductAvailOutput = (GetProductAvailOutput) responseBuilder.buildSuccessResponse(
            products, productAvailInvHelper.getProductAvailInput());
    GetProductAvailOutput expectedProductAvailOutput = productAvailInvHelper.getProductAvailOutput();

    // TODO change this to logger
    System.out.println("Size in expected " + expectedProductAvailOutput.getProductBrand().size());
    System.out.println("Size in actual " + actualProductAvailOutput.getProductBrand().size());


    Assert.assertEquals(expectedProductAvailOutput, actualProductAvailOutput);
}




@Test
public void productAvailResponseFreeSell() throws Exception {

    ResponseBuilderFactory responseBuilderFactory = ResponseBuilderFactory.createResponseBuilderFactory();
    ResponseBuilder responseBuilder = responseBuilderFactory.createResponseBuilder(PRODUCT_AVAIL_BUILDER);
    ProductAvailFreeSellHelper productAvailFreeSellHelper = new ProductAvailFreeSellHelper();
    List<Rsproducts> products = productAvailFreeSellHelper.getLOMProducts();

    // TODO change this to logger
    System.out.println("No. of products in test " + products.size());

    GetProductAvailOutput actualProductAvailOutput = (GetProductAvailOutput) responseBuilder.buildSuccessResponse(
            products, productAvailFreeSellHelper.getProductAvailInput());
    GetProductAvailOutput expectedProductAvailOutput = productAvailFreeSellHelper.getProductAvailOutput();

    // TODO change this to logger
    System.out.println("Size in expected " + expectedProductAvailOutput.getProductBrand().size());
    System.out.println("Size in actual " + actualProductAvailOutput.getProductBrand().size());

    Assert.assertEquals(expectedProductAvailOutput, actualProductAvailOutput);

}

}

也许你做了这样的事情:

import org.junit.Assert;
import org.junit.Test;


public class StatefulTest {

    private static boolean shouldSucceed = true;

    @Test
    public void test1() {
        System.out.println("shouldSucceed=" + shouldSucceed);
        Assert.assertTrue(shouldSucceed);
        shouldSucceed = false;
    }

    @Test
    public void test2() {
        System.out.println("shouldSucceed=" + shouldSucceed);
        Assert.assertTrue(shouldSucceed);
    }
}

第一个测试改变了影响第二个测试的某些状态。在本例中是一个静态字段，但它也可能是文件内容或重用的 Spring 上下文中的 bean。
