在 IntelliJ IDEA 中使用 groovy Spock 单元测试设置新的 Spring Boot Java 项目。我无法运行第一个单元测试。我从 IntelliJ 内部创建它,它位于 src/test/groovy 下。
这是单元测试。
package com.heavyweightsoftware.orders.pojo
import com.heavyweightsoftware.util.FixedDecimal
import spock.lang.Specification
class ItemOrderedTest extends Specification {
public static final String ITEM_ID = "OU812"
public static final String ITEM_NAME = "Eddie V."
public static final int ITEM_QUANTITY = 5
public static final FixedDecimal ITEM_UNIT_PRICE = new FixedDecimal(35.62, 2)
static ItemOrdered getItemOrdered() {
ItemOrdered result = new ItemOrdered()
result.itemId = ITEM_ID
result.quantity = ITEM_QUANTITY
result.itemName = ITEM_NAME
result.unitPrice = ITEM_UNIT_PRICE
return result;
}
def "GetQuantity"() {
given: "A test item"
ItemOrdered testItem = getItemOrdered()
when: "Getting Value"
int result = testItem.quantity
then: "Should be correct"
result == ITEM_QUANTITY
}
def "GetItemId"() {
given: "A test item"
ItemOrdered testItem = getItemOrdered()
when: "Getting Value"
String result = testItem.itemId
then: "Should be correct"
result == ITEM_ID
}
def "GetItemName"() {
given: "A test item"
ItemOrdered testItem = getItemOrdered()
when: "Getting Value"
String result = testItem.itemName
then: "Should be correct"
result == ITEM_NAME
}
def "GetLineTotal"() {
given: "A test item"
ItemOrdered testItem = getItemOrdered()
when: "Getting Total"
FixedDecimal result = testItem.lineTotal
then: "Should be correct"
FixedDecimal total = new FixedDecimal(178.10, 2)
result == total
}
def "GetUnitPrice"() {
given: "A test item"
ItemOrdered testItem = getItemOrdered()
when: "Getting Value"
FixedDecimal result = testItem.unitPrice
then: "Should be correct"
result == ITEM_UNIT_PRICE
}
}
这是我单击 IntelliJ 中的双箭头运行完整单元测试时的输出...

我试图找到与此相关的所有问题,但似乎没有一个有帮助。似乎没有找到我的单元测试源代码。
免责声明:我是 100% Maven 用户。 Gradle 对我来说更像是尝试和错误。但我对 Spock 的问题很感兴趣,所以我正在尝试一下。
您需要将 Groovy 插件添加到您的构建文件中:
plugins {
// ...
id 'java'
id 'groovy'
}
这也将帮助 IDEA 认识到这是一个 Groovy 项目,您可以从
src/test/groovy
运行测试。
接下来,您将得到测试编译错误,因为您使用之间存在明显的不匹配
org.spockframework:spock-bom:2.0-M1-groovy-2.5
vs.org.codehaus.groovy:groovy-all:3.0.5
,即
因此,要么降级 Groovy,要么升级 Spock。另外,M1不是最新的,最好使用M3。
// mandatory dependencies for using Spock
testCompile "org.codehaus.groovy:groovy:2.5.13"
testImplementation platform("org.spockframework:spock-bom:2.0-M3-groovy-2.5")
现在您的测试应该可以编译并运行。不过,我没有检查这样的测试。如果没有被测试的类,我无论如何都无法运行它。
摆脱
org.spockframework:spock-junit4
依赖是可选的。如前所述,Spock 2.x 基于 JUnit 5,因此,如果您的项目中没有使用 JUnit 4 功能(例如用于 PowerMock 的 @RunWith
或类似丑陋的东西)进行任何旧版 Spock 测试,则您不需要它。
也许您想更改构建文件以使其与 Spock 示例项目中的文件更相似。
2021-07-20更新:我刚刚再次打开这个示例项目,以回答另一个问题。在执行 do 时,我注意到,在使用类似
sourceCompatibility = '11'
之类的东西时需要小心,但在较旧的 JDK(例如 8)上运行构建时。这将导致以下违反直觉的 Gradle 错误:
Execution failed for task ':test'.
> No tests found for given includes: [com.heavyweightsoftware.orders.pojo.ItemOrderedTest](filter.includeTestsMatching)
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
仅当使用 Gradle 参数
--debug
运行测试时,您才会看到根本原因(日志标签和时间戳被删除):
Gradle Test Executor 31 FAILED

对我来说这个解决方案有效。只需删除:
test {
useJUnitPlatform()
}
这是我的build.gradle:
plugins {
id 'java'
id 'groovy'
id 'org.springframework.boot' version '2.4.3'
id 'io.spring.dependency-management' version '1.0.11.RELEASE'

}
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
}
}
像上面提到的亚历克斯一样,为我添加以下内容。
test {
useJUnitPlatform()
}
dependencies {
compile 'org.codehaus.groovy:groovy-all:3.0.8'
testCompile 'org.spockframework:spock-core:2.0-groovy-3.0'
}
当我移植不使用 Spock 编写的测试时,就发生了这种情况。您需要使用 Spock 关键字才能触发测试。例如,您可以开始将“expect: 1 == 1”添加到您的遗留测试中。我希望这个答案可以帮助那些错过 Spock 测试重要点的人。
