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\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 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/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 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.
