go-code-runner, v1.1

The library that implements the compiling and running of a code written in the Go programming language and running of a test case set for the compiled code (i.e. the executable file).

Running of a test case set for the compiled code (i.e. the executable file).

Change Log

• running of a test case set for the compiled code (i.e. the executable file):
  • representation of a test case:
    • input;
    • expected output;
  • checking of an actual output in each test case:
    • returning of the sentinel errors:
      • failed running — it returns on a running error;
      • unexpected output — it returns when the expected and actual outputs do not match.

Features

• saving of a code to a temporary file:
  • storing of the temporary file with the code to an individual temporary directory;
• compiling of a code written in the Go programming language:
  • automatic importing of the packages used in the code;
  • enriching of an error of the external command running by an output from the stderr stream;
• running of the compiled code (i.e. the executable file):
  • passing of a custom input as the stdin stream;
  • returning of an output from the stdout stream;
  • enriching of an error of the external command running by an output from the stderr stream;
