Brief summary

Execute Command in Terminal fails in UEFI Shell.

How reproducible

No response

How to reproduce

robot -v snipeit:no -L TRACE -v rte_ip:192.168.10.112 -v config:minnowboard-turbot assessment/txe-secure-boot.robot

Expected behavior

The keyword should execute the command and return the output.

Actual behavior

The keyword fails - for some reason it waits for an empty string instead instead of prompt.

Additional context

As of now, executing commands in UEFI Shell requires running the following 3 keywords (after previously setting the prompt):

Write Bare Into Terminal    <command>
Press Enter
${out}=    Read From Terminal Until Prompt

A new keyword should be defined, which achieves the above.

We enter into UEFI shell in these cases:

./dasharo-security/secure-boot.robot:150:    Enter UEFI Shell
./dasharo-security/secure-boot.robot:167:    Enter UEFI Shell
./dasharo-security/secure-boot.robot:184:    Enter UEFI Shell
./dasharo-security/secure-boot.robot:226:    Enter UEFI Shell
./dasharo-security/secure-boot.robot:238:    Enter UEFI Shell
./lib/secure-boot-lib.robot:219:Enter UEFI Shell
./assessment/txe-secure-boot.robot:35:    Enter UEFI Shell

But it seems we only execute some commands in shell in the last two, so only these should be fixed.

Steps to solve this:

• [ ] Create new file under self-tests/terminal.robot
  • [ ] Test should enter UEFI shell and execute some command (even help or anything), reading it's output
  • Try to do this via Execute Commanad in Terminal and via workaround proposed in the issue, to understand the problem
• [ ] Improve the Execute Command In Terminal to properly handle it, or introduce a new keyword for executing command in UEFI shell, and place it under lib/terminal.robot
• [ ] Replace all occurencies with a new kwd
