Python2.7中xml.etree.ElementTree的findall无法返回全部匹配节点

你的代码调用findall匹配到所有符合条件的testsuite节点后，仅通过索引[0]获取了第一个节点的属性值，没有遍历所有节点做累加，因此统计结果只包含第一个测试套件的数值。

import os
import xml.etree.ElementTree as ET
import sys

filename = sys.argv[1]
filepath = os.path.join(os.path.dirname(os.path.realpath(__file__)),filename)  

print("Processing File: ", format(filepath))
    
tests = 0
failures = 0
errors = 0
skipped = 0
issues = 0

file = open(filepath, "r")

tree = ET.parse(file)
root = tree.getroot()

# 遍历所有匹配节点累加数值
for node in root.findall(".//*[@tests]"):
    tests += int(node.attrib.get("tests"))
for node in root.findall(".//*[@failures]"):
    failures += int(node.attrib.get("failures"))
for node in root.findall(".//*[@errors]"):
    errors += int(node.attrib.get("errors"))
for node in root.findall(".//*[@skipped]"):
    skipped += int(node.attrib.get("skipped"))

issues += int(failures) + int(errors)
status = "PASSED"
        
if issues > 0:
    status = "FAILED"

print("tests: ", format(tests))
print("issues: ", format(issues))
print("status: ", format(status))
sys.exit(issues)

你提供的测试XML中共有3个testsuite节点：

• 测试用例总数：16 + 1 + 20 = 37
• 错误总数：0 + 1 + 4 = 5
  修正后代码运行输出和你预期的结果完全一致。
