How to spawn command - wiwanek/Expect.NET GitHub Wiki

Expect.Spawn(ISpawnable) function creates a Session object with implementation of ISpawnable interface. Spawned sessions can be automated using Session methods such as Session.Expect() and Session.Send().

To automate console application should be used CommandSpawnable class. The CommandSpawnable wraps System.Diagnostics.Process class to run and control local application.

CommandSpawnable has three constructor variants:

• ProcessSpawnable(string command) - accepts command to execute as string. Example:

Session s = Expect.Spawn(new ProcessSpawnable("cmd.exe"));

• ProcessSpawnable(string command, string arguments) - accepts command to execute as a string and command-line arguments as a string. Example:

Session s = Expect.Spawn(new ProcessSpawnable("cmd.exe", "\?"));

• ProcessSpawnable(Process process) - accepts Process object with configured filename. Process should not be started prior passing to constructor - it will be started during creation of session. Example:

string filename = "testFileName";
string args = "arg1 arg2";
Process p = new Process();
p.StartInfo.FileName = filename; // It's mandatory
p.StartInfo.Arguments = args; // It's optional
ProcessSpawnable proc = new ProcessSpawnable(p);
Session s = Expect.Spawn(proc);
