python之我们可以限制与 testtools.ConcurrentStreamTestSuite 并行运行的测试数量吗

我正在从 unittest 转换为 testtools 以并行运行我的 Python 测试。

我想知道在使用 testtools.ConcurrentStreamTestSuite 时是否有办法限制同时运行的测试数量？我很快就会有数百个测试，并且需要将执行限制为一次最多 10 个。其余的将排队等待线程释放时执行。

如果是这样，您能否分享一些展示如何做到这一点的代码片段？

请您参考如下方法:

我已经清理了逻辑，这是该函数的新版本(效果更好):

def split_suite_into_chunks(num_threads, suite): 
    # Compute num_threads such that the number of threads does not exceed the value passed to the function 
    # Keep num_threads to a reasonable number of threads 
    if num_threads < 0: num_threads = 1 
    if num_threads > 8: num_threads = 8 
    num_tests = suite.countTestCases() 
    s = [] 
    s_tmp = unittest.TestSuite() 
    n = round(num_tests / num_threads) 
    for case in suite: 
        if n <= 0 and s_tmp.countTestCases() > 0: 
            s.append([s_tmp, None]) 
            num_threads -= 1 
            num_tests -= s_tmp.countTestCases() 
            s_tmp = unittest.TestSuite() 
            n = round(num_tests / num_threads) 
        s_tmp.addTest(case) 
        n -= 1 
    if s_tmp.countTestCases() > 0: 
        if s_tmp.countTestCases() > 0: s.append([s_tmp, None]) 
        num_tests -= s_tmp.countTestCases() 
    if num_tests != 0: print("Error: num_tests should be 0 but is %s!" % num_tests) 
    return s
