Now click on the Launch Child Process button. You will notice that C++ Coverage Validator is not collecting data. The first time testAppFromOtherProcess.exe is launched it will be monitored. Select testAppFromOtherProcess.exe in the Application to monitor combo. The Application to monitor combo will now have additional entries in it. Your dialog should look like the one shown below.Ĭlick OK to close the Application To Monitor dialog.Ĭlick OK to close the Applications To Monitor dialog. You can remove any programs you don't want to monitor with the Remove and Remove All buttons. C++ Coverage Validator will identify any other executables in the same folder and add these to the list of target programs you may want to monitor. Choose our launch program testAppOtherProcessCpp.exe using Browse. The Application To Monitor dialog is displayed. We need to add our target program to the list of programs to monitor.
The Applications To Monitor dialog is displayed. button to the right of the Application to monitor combo box. To allow us to monitor other programs we need to edit the list of applications we can monitor. This is the same program as you just selected with the File dialog. Once a file has been chosen a default value will be selected for the Application to Monitor. button and selecting the file with the File dialog. From the launch dialog, select the program to launch using the Browse. We do this from the launch dialog (or launch wizard). SetDlgItemInt(IDC_STATIC_VALUE, v, FALSE) īefore we can collect code coverage we need to tell C++ Coverage Validator about the target program and the program that is going to launch it. GetExitCodeProcess(stProcessInfo.hProcess, &v) WaitForSingleObject(stProcessInfo.hProcess, INFINITE) wait until complete then get exit code
StStartInfo.dwFlags = STARTF_USESHOWWINDOW Memset(&stProcessInfo, 0, sizeof(PROCESS_INFORMATION)) Memset(&stStartInfo, 0, sizeof(STARTUPINFO)) Void CtestAppOtherProcessCppDlg::OnBnClickedOk()Ĭommandline += _T("testAppFromOtherProcess.exe") The code for launching the child process looks like this: The parent C++ program is a simple MFC dialog that collects two values and launches the test program. If less than two arguments are supplied they default to 10. It takes two numbers and calculates the sum of all the products. Once I’ve explained this for C++, I’ll also provide examples for programs launched from Java and for programs launched from Python.

I’m first going to show how you do this with the GUI, then I’ll show you how to do this with the command line.įor the purposes of this blog post I’m going to use a test program called testAppFromOtherProcess.exe as the child program and testAppOtherProcessCpp.exe as the parent process. We’ll be using C++ Coverage Validator to collect the code coverage.įor example you may have a control process that launches helper programs to do specific jobs and you wish to collect code coverage data for one of the helper programs. In this blog post I’m going to explain how to collect code coverage for a process that is launched by another process.
