使用Python或Java自动化HP Quality Center

Question

我们有一个使用惠普质量中心的项目，我们面临的一个常见问题是人们没有更新有关缺陷的评论。

所以我想我们可以提出一个小脚本或工具，可以用来定期抛出提醒并强迫用户更新评论。

我遇到了Open Test Architecture API，并且想知道我能看到的是否有任何好的Python或java示例。

由于 哈

Answer 1

使用Python（win32com）通过OTA

连接到HP Quality Center的示例

HP Quality Center公开了一个名为OTA的基于com的API。

此文档可从QC服务器下载 （OTA_API_Reference.chm）（奇怪的是在网上很难找到）

文档使用VBScript（官方支持的QC内部语言） 你需要在心理上翻译成Python。这通常很简单，但是 存在一些问题。

您需要在您的计算机上安装Quality Center本地代码，这是在您的Windows PC上 如果你能通过网络界面进入QC。

您还需要知道服务器的URL以及您的用户名和密码以及域名 您正在进行的QC项目。

from win32com.client import Dispatch

conn = get_QCConnection()

for bug in get_bugs(qcConn):
    print bug.Title

put_QCConnection(conn)

#below code needs to be in seperate module or at least above the fold but here 
# for clarity

def get_QCConnection():
    '''Get the hardcoded connection to the server and domain.
    Can be made a "real" engine if you try hard.
    Use makepy utility to determine if the version number has changed (TDApiOle80)
    but this works to current version'''

    QCConnection = Dispatch("TDApiOle80.TDConnection")
    url = "http://qc.example.com/qcbin"
    QCConnection.InitConnectionEx(url)
    QCConnection.login("USER", "PASS")
    QCConnection.Connect("google_projects", "Google_Chrome")    
    return QCConnection

def put_QCConnection(qcConn):
    #If one person logged in to QC changes *anything* on a bug,
    # they hold a global lock on writing to that bug till 
    # thier session times out, so really really remember to logout
    # its painful to wait for your own session to time out

    qcConn.Logout()

def get_bugs(qcConn):
    '''just following boiler plate from vbscript
    PS the SetFilter is not in QTA API, it uses Filter.  
    But due to the workarounds in 
    the very brilliant pythoncom code it supplies a virtual wrapper class
    called SetFilter - this is one of those gotchas '''

    BugFactory = qcConn.BugFactory
    BugFilter = BugFactory.Filter

    BugFilter.SetFilter(u"Status", "New") 
    #NB - a lot of fields in QC are malleable - and vary from site to site. 
    #COntact your admins for a real list of fields you can adjust
    buglist = BugFilter.NewList()
    return buglist       

这不是前进的坏基础，但是我为缺陷创建了一个虚拟类并运行如下：

dfcts = [defect(b) for b in buglist]

然后我可以将工作人员代码放入缺陷类并保持整洁。 您要做的一件事是继续访问python包装器类内部的原始qc错误。

可能查看此主题的其他人的信息。

开始这一切你需要安装pywin32，就像从这里http://sourceforge.net/projects/pywin32/files/pywin32/Build216/

一样

首先，您需要导入pywin32

'''@author: www.qcintegration.com  @mailto:contact@qcintegration.com'''
import pywintypes
import win32com.client as w32c
from win32com.client import gencache, DispatchWithEvents, constants

然后作为第二个操作，我在此处包含登录服务器的操作

def connect_server(qc, server):
        '''Connect to QC server
        input = str(http adress)
        output = bool(connected) TRUE/FALSE  '''
        try:
            qc.InitConnectionEx(server); 
        except:
            text = "Unable connect to Quality Center database: '%s'"%(server); 
        return qc.Connected;

def connect_login(qc, username, password):
    '''Login to QC server
    input = str(UserName), str(Password)
    output = bool(Logged) TRUE/FALSE  '''
    try:
        qc.Login(username, password);
    except pywintypes.com_error, err:
        text = unicode(err[2][2]);
    return qc.LoggedIn;

def connect_project(qc, domainname, projectname):
    '''Connect to Project in QC server
    input = str(DomainName), str(ProjectName)
    output = bool(ProjectConnected) TRUE/FALSE  '''

    try:
        qc.Connect(domainname, projectname)
    except pywintypes.com_error, err:
        text = "Repository of project '%s' in domain '%s' doesn't exist or is not accessible. Please contact your Site Administrator"%(projectname, domainname); 
    return qc.ProjectConnected;

包含OTAapi dll文件的所有方法的第二个

def qc_instance():
        '''Create QualityServer instance under variable qc
        input = None
        output = bool(True/False)'''
        qc= None;
        try:
            qc = w32c.Dispatch("TDApiole80.TDConnection");
            text = "DLL QualityCenter file correctly Dispatched"
            return True, qc;
        except:
            return False, qc;

然后连接到QCserver的主要方法

def qcConnect(server, username, password, domainname, projectname):
    print("Getting QC running files");

    status, qc = qc_instance();
    if status:
        print("Connecting to QC server");
        if connect_server(qc, server):
            ##connected to server
            print("Checking username and password");
            if connect_login(qc, username, password):
                print("Connecting to QC domain and project");
                if connect_project(qc, domainname, projectname):
                    text = "Connected"
                    connected = True;
                    return connected, text;
                else:
                    text = "Not connected to Project in QC server.\nPlease, correct DomainName and/or ProjectName";
                    connected = False;
                    return connected, text;
            else:
                text = "Not logged to QC server.\nPlease, correct UserName and/or Password";
                connected = False;
                return connected, text;
        else:
            text = "Not connected to QC server.\nPlease, correct server http address"; 
            connected = False;
            return connected, text;
    else:
        connected = False;
        text = "Unable to find QualityCenter installation files.\nPlease connect first to QualityCenter by web page to install needed files" 
        return connected, text;

最后如何使用示例在一个地方执行所有这些方法

if __name__ == "__main__":
    server= r"http://qualitycenterServer:8080/qcbin"
    username= "alex_qc"
    password= ""
    domainname= "DEFAULT"
    projectname= "QualityCenter_Demo" 

    connection_status, text  = qcConnect(server, username, password, domainname, projectname);
    print "connection_status:", connection_status

Answer 3

我不确定Java是否有任何好的示例，因为OTA不能直接被Java使用，它需要像JIntegra那样的Java到COM桥接。

关于Python，你可以使用Python COM api。然后任何OTA示例都可以。你有很多关于OTA的QC文档。

但我认为这里真正的问题是，你为什么要用Python或Java来做呢？为什么不使用它的工作流功能直接在QC中编写您需要的内容。这将允许您在VBScript中编写逻辑，并在用户操作的QC UI中调用它。例如，您可以绑定到缺陷/错误的Post事件，并检查是否有注释，如果没有提示用户直接发送消息。

Answer 4

如果您想从Linux访问它而不运行Windows COM组件，则有REST API to HPQC（ALM11和更新版本）。

这是一个引入＆＃34;要求的示例＆＃34;在验证后记录（＃1202）。

import requests
session = requests.session()
user='hpqc'
password='xxxxx'
r = session.get("http://hpqc-server:8080/qcbin/authentication-point/authenticate",auth=(user,password))

r = session.get("http://hpqc-server:8080/qcbin/rest/domains/Foo/projects/Bar/requirements/1202")
print(r.text)

从XML解析r.text留作练习。

Answer 5

虽然您已经要求使用基于Python或Java的解决方案，但是共享以下VBA代码，您可以使用HPQC / ALM的脚本编辑器（缺陷模块脚本）来实现目标。

Function Bug_FieldCanChange(FieldName, NewValue)

 On Error Resume Next

 if not changed then
 strCommentBeforeUpdate = Bug_Fields("BG_DEV_COMMENTS").Value
 end if

 If FieldName = "BG_DEV_COMMENTS" and blnAddCommentClicked = False Then
    Msgbox "Cannot update the comments." & Chr(13)& "Changes made will not be saved."&Chr(13)& "Please use 'Add comment' button to insert new comment." &Chr(13)& " Or click Cancel without saving."
    blnUpdateCommentError = true
    blnAddCommentClicked = False
    changed = true
  End If
Bug_FieldCanChange = DefaultRes 

End Function

您可以使用新的测试并选择允许脚本运行的类型（VPXP_API）。好的是，您已准备好在QC中拖动函数定义，而不必非常依赖doc。 我已经在Python中执行了一个实现，从QC中运行一些脚本仍然使用它的API，但是通过QC测试，这很方便直接检索结果（输出）等。通过一些shell命令，然后可以调用任何脚本服务器等...
