我们已经实施了Spock + Db单元框架作为自动化单元测试的一部分。
我们现在有2000个测试用例(功能),用于150个规格和DbUnit。
在这里,我们在DB中添加所需的条目,然后测试每个方法的行为。
我们观察到,执行这些测试用例需要大约2小时和30分钟。
我有时间戳setup
夹具并在特征方法中添加时间戳。以下是我的观察:
allergy.dao.AllergyFormDAOSpec > Get Allergy Form STANDARD_OUT
setup method execution started at : Fri Jan 12 19:00:42 IST 2018
allergy.dao.AllergyFormDAOSpec > API to get Allergy Form STANDARD_OUT
Feature method execution started at : Fri Jan 12 19:00:44 IST 2018
Feature method execution ended at: Fri Jan 12 19:00:45 IST 2018
Total time taken to run the one test case: 242
cleanup method execution started at : Fri Jan 12 19:00:45 IST 2018
Total time taken to run a feature method : 2531
在这里,我观察到在安装后加载一个特征方法平均需要2-4秒。但是,原始测试用例执行时间不到一秒。
我想知道我是否能指出这里有什么延迟?因为,2000个测试用例的3秒意味着Spock所花费的时间几乎是1小时和30分钟,而不是真正的功能执行。
总结一下,我们希望减少Spock测试用例在每天运行时所花费的总时间。

这个问题确实过于宽泛,无法提供足够的信息来提供合格的答案。但是,我可以说Spock本身应该非常快(不像'原始'JUnit那么快,毕竟它仍然很常规,但真的足够快,无法进行测试)。
从您的问题来看,您似乎怀疑Spock是一个瓶颈,所以,例如,您可以放置一个空的Spock测试并在DbUnit启用的测试旁边测量它的执行,我可以向您保证,您将获得的时间将是微不足道的。
所以我认为原因是在安装/清理期间,DbUnit调用了一些与数据库相关的代码(可能是模式生成/表格填充和/或删除),这需要花费很多时间。因此,我的第二次尝试只是打印在测试期间运行的SQL查询,可能您会发现其中许多在安装方法期间运行。
另一个可能的原因是,在进行测试时,在测试之前插入的数据太多了。
而另一个可能的原因是你正在运行测试的数据库太慢(网络速度慢,数据库本身太忙了)。
现在有什么解决方案呢? :)您可能想看看Spring的方法来测试数据访问层+如何进行初始设置。由于它远远超出了问题的范围,我不会在这里谈论春天太多,但只是作为一个想法:
如果缓慢的原因是数据库服务器,那么(除了明显的建议,如“更改您的RDBMS”),您可以尝试在同一台机器中的docker中运行数据库/甚至在使用TestContainers在本地测试开始之前启动数据库。
答案实际上非常简单:您忘记测量主规格的设置时间。也许你假设儿童规范中的setup()
方法会覆盖其父规范的setup()
方法。但在Spock中却没有!所有的
setupSpec()
setup()
cleanup()
cleanupSpec()
类层次结构中的所有规范将按以下顺序执行:首先是基类,然后是子类。
让我用一个原始的例子告诉你我在说什么:
主规格:
为什么是线程局部静态变量?好吧,也许你正在同时运行你的测试。对于这个简单的例子,没有必要。
package de.scrum_master.stackoverflow
import spock.lang.Specification
import static System.currentTimeMillis
class MasterSpec extends Specification {
static ThreadLocal<Long> startMillis = new ThreadLocal<>()
def setupSpec() {
startMillis.set(currentTimeMillis())
sleep 50
println "BaseSpec.setupSpec: " + (currentTimeMillis() - startMillis.get())
}
def cleanupSpec() {
sleep 50
println "BaseSpec.cleanupSpec: " + (currentTimeMillis() - startMillis.get())
}
def setup() {
sleep 50
println "BaseSpec.setup: " + (currentTimeMillis() - startMillis.get())
}
def cleanup() {
sleep 50
println "BaseSpec.cleanup: " + (currentTimeMillis() - startMillis.get())
}
}
衍生规格:
为什么叫DerivedTest
这个名字?只是因为我的Maven构建配置的方式是基于默认名称*Test
(Surefire单元测试)或*IT
(故障安全集成测试)查找测试。
package de.scrum_master.stackoverflow
import spock.lang.Unroll

expect:

where:
id << ["A", "B"]
}
}

你能看到执行的顺序以及每一步消耗的时间吗?
我会说,你在主规范中的复杂操作(读取配置文件,初始化和填充数据库等)
为了分析这个问题的根本原因,我们确实在下面的场景中运行了一个差事:
1)没有任何Db或模拟依赖项的1000个Spock测试用例(PowerMock)

3)仅有Dbunit的1000个Spock测试用例。 (通常,我们在测试用例中插入平均15-20个表项。这里,我们添加了相同的)
示例代码解释方案:

def result =objMath.addNumber(a,b)
then: "Result should be 15"
result==15
}
def "API to test subrtaction of two numbers"() {
given :"a and b"
def a=10
def b=5
when: "Math.subtractNumber is called with given values"
def result =objMath.subtractNumber(a, b)
then: "Result should be 5"
result==5
}
def "API to test multiplication of two numbers"() {
given :"a and b"
def a=10
def b=5
when: "Math.multiplyNumber is called with given values"
def result =objMath.multiplyNumber(a,b)
then: "Result should be 50"
result==50
}
def "API to test division two numbers"() {

def a=10
def b=5

def result =objMath.divisionNumber(a,b)
then: "Result should be 2"
result==2
}
def "API to test whether given both numbers are equal - Affirmative"() {
given :"a and b"
def a=10
def b=10
when: "Math.equalNumber is called with given values"
def result =objMath.equalNumber(a,b)
then: "It should return true"
result==true
}
def "API to test whether given both numbers are equal - Negative"() {

def a=10
def b=11
when: "Math.equalNumber is called with given values"
def result =objMath.equalNumber(a,b)
then: "It should return false"
result==false
}
}
我们得出一个结论,Spock没有花时间运行测试用例,但Power Mock做了仪器qazxsw poi和DbUnit(使用反射加载一切)是瓶颈。
解决方案:我们将使用内部框架来插入/删除数据库数据而不是DbUnit。此外,我们用SO Link取代了Power Mock
最终结果:正如我在问题中发布的总时间从2小时和30分钟开始,现在已经减少到这1000个测试用例的6分钟。 :)
