[英]Scons running py.test in different subdirectories
We have a large repository containing several Python packages(*). 我们有一个包含几个Python软件包(*)的大型存储库。 I want scons to run py.test in each of the sub directories and not from the project root. 我希望scons在每个子目录中运行py.test ,而不是从项目根目录运行。 This is proving rather frustrating. 事实证明,这令人沮丧。 Currently, I have this action with all error checking removed: 目前,我已执行此操作,并删除了所有错误检查:
def runTests (target = None, source = None, env = None):
cmd = which(env['TEST_RUNNER'])
if cmd:
retCode = True
for path in env['TEST_DIR_LIST']:
print 'Doing directory %s:' % (path)
retCode = retCode and subprocess.call([cmd], cwd=path)
env.Exit(retCode)
Which I call as in the SConstruct
file: 我在SConstruct
文件中这样称呼它:
runTestsCmd = env.Command('runTests', None, Action(runTests, "Running tests"))
AlwaysBuild(runTestsCmd)
Alias('test', runTestsCmd)
And in each SConscript
file, I have this: 在每个SConscript
文件中,我都有:
env.Append(TEST_DIR_LIST = ['PackageDirectory'])
What I get is that only one instance of py.test is run. 我得到的是仅运行py.test的一个实例。 I can see the "Doing directory X" messages but no run of py.test. 我可以看到“正在执行目录X”消息,但没有运行py.test。
Clearly, there is a need to not clone the environment in SConscript or if the env is cloned, making sure that the addition to TEST_DIR_LIST happens on original env. 显然,没有必要在SConscript中克隆环境,或者如果克隆了env,请确保在原始env上添加了TEST_DIR_LIST。
So, my questions are two fold: 因此,我的问题有两个:
(*) Yes, we are looking at changing this. (*) 是,我们正在考虑对此进行更改。 No, it will not happens soon enough so I do need the above. 不,它不会足够快地发生,所以我需要上面的内容。
The problem is the line: 问题是这一行:
retCode = retCode and subprocess.call([cmd], cwd=path)
subprocess.call
returns 0 (which evaluates to False
) on success. subprocess.call
将返回0(其值为False
)。 You need to insert a not
or maybe do a proper check like this: 您需要插入一个not
或进行如下适当检查:
retcode = subprocess.call([cmd], cwd=path)
if retcode != 0:
print ("failed ...")
break # or not break if you want to continue anyway
