在当今的自动化测试领域,结合Web UI和API接口测试已成为提升测试覆盖率和效率的关键。Playwright作为一个强大的自动化测试工具,除了在Web UI测试中大放异彩,还能与Python结合,实现强大的API接口测试功能。本文将带你探索如何使用Playwright和Python进行高效的API接口测试。
Playwright除了在Web UI测试中的出色表现,如何通过与Python结合,开展API接口测试,并实现高效的自动化测试?
playwright也是可以做接口测试的,但个人觉得还是没有requests库强大,但和selenium相比的话,略胜一筹,毕竟支持API登录,也就是说可以不用交互直接调用接口操作了。
既然是API的测试了,那肯定就别搞UI自动化那套,搞什么浏览器交互,那叫啥API测试,纯属扯淡。
也不像有些博主更懒,直接贴的官方例子,难道我用你再帮我复制一次?
来下面,说明下使用playwright如何做API测试?
示例代码如下:
playwright.request.new_context()
没错,实例化后,就是调API,看吧,其实也不是很难是不是?
这里用我自己写的学生管理系统的部分接口来做演示,并对部分常用api做以说明,代码示例都是用同步的写法。
示例如下:
def testQueryStudent(playwright: Playwright):
"""
查询学生
"""
url = 'http://localhost:8090/studentFindById'
param = {
'id': 105
}
request_context = playwright.request.new_context()
response = request_context.get(url=url, params=param)
assert response.ok
assert response.json()
print('n', response.json())
效果:

示例代码:
def testAddStudent(playwright: Playwright):
"""
新增学生
:return:
"""
url = 'http://localhost:8090/studentAdd'
request_body = {
"className": "banji",
"courseName": "wuli",
"email": "ales@qq.com",
"name": "ales",
"score": 70,
"sex": "boy",
"studentId": "92908290"
}
header = {"Content-Type": "application/json"}
request_context = playwright.request.new_context()
response = request_context.post(url=url, headers=header, data=request_body)
assert response.ok
assert response.json()
print('n', response.json())
效果:

示例代码:
def testUpdateStudents(playwright: Playwright):
"""
修改学生
"""
url = 'http://localhost:8090/studentUpdate/100'
param = {
'studentId': "id" + str(100),
'name': "name" + str(100),
'score': 100,
"sex": "girl",
"className": "class" + str(100),
"courseName": "course" + str(100),
"email": str(100) + "email@qq.com"
}
request_context = playwright.request.new_context()
response = request_context.put(url=url, form=param)
assert response.ok
assert response.json()
print('n', response.json())
效果:

示例代码:
def testDeleteStudents(playwright: Playwright):
"""
删除学生
"""
url = 'http://localhost:8090/studentDelete/' + str(105)
request_context = playwright.request.new_context()
response = request_context.delete(url=url)
assert response.ok
assert response.json()
print('n', response.json())
效果:

这个是特例吧,按照官方给的方法,我真的是死活也不能成功,一直都是提示上上传文件不能为空,也不到为啥,结果我用了一个替代方案,就是抓包模拟的构造入参,才成功,也是曲折呀。
示例代码:
def test_upload_file(playwright: Playwright):
'''
上传文件
:param playwright:
:return:
'''
# 创建请求上下文
request_context = playwright.request.new_context()
# 定义上传文件的URL
upload_url = "http://localhost:8090/fileUpload"
# 文件路径
file_path = "d:/demo.txt"
# 获取文件名和MIME类型
filename = file_path.split('/')[-1]
mime_type, _ = mimetypes.guess_type(file_path)
if not mime_type:
mime_type = 'application/octet-stream'
# 读取文件内容
with open(file_path, 'rb') as file:
file_content = file.read()
# 构造multipart/form-data的边界字符串
boundary = '---------------------' + str(random.randint(1e28, 1e29 - 1))
# 构造请求体
body = (
f'--{boundary}rn'
f'Content-Disposition: form-data; name="file"; filename="{filename}"rn'
f'Content-Type: {mime_type}rnrn'
f'{file_content.decode("utf-8") if mime_type.startswith("text/") else file_content.hex()}'
f'rn--{boundary}--rn'
).encode('utf-8')
# 设置请求头
headers = {
'Content-Type': f'multipart/form-data; boundary={boundary}',
}
# 发起POST请求
response = request_context.post(upload_url, data=body, headers=headers)
# 检查响应
assert response.status == 200, f"Upload failed with status: {response.status}"
assert response.ok
assert response.json()
print('n', response.json())
效果:

官方写法:
# 读取文件内容
with open(file_path, 'rb') as file:
file_content = file.read()
response = request_context.post(upload_url, multipart={
"fileField": {
"name": "demo.txt",
"mimeType": "text/plain",
"buffer": file_content,
}
})
print('n', response.json())
效果:

官方写法,我不知道为啥就是不成功,有大侠知道吗,还请帮忙给个例子,小弟不胜感激!
