Text UI Testing Tutorial

  1. Create a folder [project root]\text-ui-test

  2. Add a runtest.bat (if you are on Windows) or runtest.sh (if you are on a *nix OS) into the folder, containing the script below.
    runtest.bat:

    @ECHO OFF
    
    REM create bin directory if it doesn't exist
    if not exist ..\bin mkdir ..\bin
    
    REM delete output from previous run
    del ACTUAL.TXT
    
    REM compile the code into the bin folder
    javac  -cp ..\src -Xlint:none -d ..\bin ..\src\main\java\dukeclasses.Duke.java
    IF ERRORLEVEL 1 (
        echo ********** BUILD FAILURE **********
        exit /b 1
    )
    REM no error here, errorlevel == 0
    
    REM run the program, feed commands from input.txt file and redirect the output to the ACTUAL.TXT
    java -classpath ..\bin dukeclasses.Duke < input.txt > ACTUAL.TXT
    
    REM compare the output to the expected output
    FC ACTUAL.TXT EXPECTED.TXT
    

    runtest.sh:

    #!/usr/bin/env bash
    
    # create bin directory if it doesn't exist
    if [ ! -d "../bin" ]
    then
        mkdir ../bin
    fi
    
    # delete output from previous run
    if [ -e "./ACTUAL.TXT" ]
    then
        rm ACTUAL.TXT
    fi
    
    # compile the code into the bin folder, terminates if error occurred
    if ! javac -cp ../src -Xlint:none -d ../bin ../src/main/java/dukeclasses.Duke.java
    then
        echo "********** BUILD FAILURE **********"
        exit 1
    fi
    
    # run the program, feed commands from input.txt file and redirect the output to the ACTUAL.TXT
    java -classpath ../bin dukeclasses.Duke < input.txt > ACTUAL.TXT
    
    # compare the output to the expected output
    diff ACTUAL.TXT EXPECTED.TXT
    if [ $? -eq 0 ]
    then
        echo "Test result: PASSED"
        exit 0
    else
        echo "Test result: FAILED"
        exit 1
    fi
  3. Update the javac and java commands in the script to match the name/location of your main class.

  4. Add an EXPECTED.txt to the same folder, containing the expected output.

  5. Add an input.txt containing the input commands.

  6. Run the .bat/.sh file to execute the test.
