It runs the process in non-interactive way

[Chris Murphy]

Hi there,

First of all, thank you for such amazing library.

In short: I used it however it run the process in "non-interactive way" so im unable to use it in the intended way.

In detail: I'm trying to automate a library which works by asking different questions and then do the process. If i run it in simple commandline and manually enter everything it simply works. However when i used it with your library then it somehoe know that its running in non-interactive mode and thus doest work.

Please advise

Hi,

Can you show some code examples? I’m curious how do you attach to the process running your library.

Regards,

-Alexey

Hi Alexey,

Here is my code, im trying to automate Fastlane Library

Process process = Runtime.getRuntime().exec("/bin/bash");

Expect expect = new ExpectBuilder()
        .withInputs(process.getInputStream())
        .withOutput(process.getOutputStream())
        .withTimeout(10, TimeUnit.SECONDS)
        //.withExceptionOnFailure()
        .withEchoOutput(outoutInfo)
        .build();


expect.sendLine("cd /Volumes/BOOTCAMP/MyBuild");

expect.sendLine("ls");


Result result = expect.expect(contains("iPhone"));




expect.sendLine("fastlane init");


result = expect.expect(contains("Your Apple ID (e.g. fast...@krausefx.com)"));

System.out.println(result.toString());


expect.sendLine("em...@email.com");


result = expect.expect(contains("Your Apple ID (e.g. fast...@krausefx.com)"));

It looks like you are not waiting for the command to execute.

Add expect.expect(contains(PROMPT)) after each send line statement. Have a look at these examples:

[Chris Murphy]

I'm actually waiting.

[Alexey Gavrilov]

OK, at least you are not waiting after ‘cd’, so doubt that ‘ls’ is working as expected.

[Chris Murphy]

Please check this post, as you can see the fastlane cli itself knows that whether its running in interactive (manual) or non-interactive (your library).

What do you advise?

Hi, 

You should be able to start a process from your Java program in the same way as if you run it in the terminal.

Make sure you have the same set of the environment variables in the bash shell session.

Also consider starting fastline as Java process avoid running bash shell.

Hope it helps,

Alexey

Hi Alexy,

Also consider starting fastline as Java process avoid running bash shell.

Can you please explain with a code example how do i do it?

My current code is this

Process process = Runtime.getRuntime().exec("/bin/bash");

Expect expect = new ExpectBuilder()
        .withInputs(process.getInputStream())
        .withOutput(process.getOutputStream())
        .withTimeout(10, TimeUnit.SECONDS)
        //.withExceptionOnFailure()
        .withEchoOutput(outoutInfo)
        .build();

Thanks

Replace /bin/bash with the full path to the tool you wish to interact with.

[Chris Murphy]

Hi Alexy,

I just did that and it opens the macOS Terminal, however Terminal app does nothing.

Process process = Runtime.getRuntime().exec(

    //        "/bin/bash"
        "/Applications/Utilities/Terminal.app/Contents/MacOS/Terminal"

);

I see following in IntelliJ output 

SimpleResult{succeeded=false, before='null', group='null', input='', canStopMatching=false}

SimpleResult{succeeded=false, before='null', group='null', input='', canStopMatching=false}

Please advise.

[Alexey Gavrilov]

I mean the fastlane process, not terminal.

[Chris Murphy]

Sorry for noobish complaint, but i dont know how to directly run it.

Fastlane is a Ruby Gem i guess, which even downloads using Terminal and run using terminal.

Can you please guide how can i directly run it?

Hi all,

I need some help.

I want to automate an interactive application and it needs 'up' and 'Down arrows'.

I want to select from the menu by using the up and down arrows.

can someone please suggest how to send the up and down arrow buttons in expect.sendLine() or expect.send() ?

Thanks

Hi Team,

I need to validate the console text with the expected string.

eg. if I run the menu.py it will show the menu.
I want to store that menu in a string and validate it in my menu string.
