ruby_test_student_grader

A Ruby gem for generating academic test reports in HTML format. Initially designed for automated grading of university programming assignments, with flexibility to adapt to different testing frameworks.

Current Status: Early Development (Beta)
Primary Use: Automated evaluation of academic coding tasks
Future Goal: Modular system for diverse testing scenarios

Add to your Rails Gemfile:

gem 'ruby_test_student_grader', path: '/path/to/gem/directory'

Then run:

bundle install

From RubyGems (Once Published)

gem install ruby_test_student_grader

Configure in your test helper:

 test/test_helper.rb

require 'ruby_test_student_grader'

Minitest.after_run do
  RubyTestStudentGrader::Reporter.new(
    total_score,      # Calculated score
    max_score,        # Maximum possible score
    failed_tests,     # Array of failed test names
    automated_feedback # Generated feedback summary
  ).generate
end

See README_PROBAR.md for a step-by-step guide. Quick summary:

# HTML and CSV
reporter = RubyTestStudentGrader::Reporter.new(5.2, 6.0, ["test_model"], "Good job", course_name: "IIC2143")
reporter.generate
reporter.generate_csv("public/test_report.csv")

# PDF (optional, requires prawn)
reporter.generate_pdf("public/test_report.pdf")

# Multiple students
students = [ { id: 1, name: "Alice", total_score: 5.2, max_score: 6.0, failed_tests: ["test_model"], feedback: "OK" } ]
RubyTestStudentGrader::ClassReporter.new(students, course_name: "IIC2143", output_dir: "public/reports").generate_all

# Similarity
RubyTestStudentGrader::Similarity.jaccard("def a;1;end", "def b;1;end", k: 5)

Use the demo script to verify everything end-to-end.

• Path: scripts/demo.rb
• It will:
  • Generate HTML and CSV in public/
  • Try to generate PDF (if prawn is installed)
  • Create per-student reports and an index under public/reports/
  • Print a code similarity score

Run:

bundle exec ruby scripts/demo.rb

Optional (for PDF):

bundle add prawn

Tip: set a course name for the report via env var (optional):

export COURSE_NAME="IIC2143"

• CSV export: RubyTestStudentGrader::Reporter#generate_csv("public/test_report.csv")
• PDF export (optional, requires prawn): RubyTestStudentGrader::Reporter#generate_pdf("public/test_report.pdf")
• Course name in HTML/CSV/PDF: pass course_name: "IIC2143" to the constructor or set COURSE_NAME in your environment.

students = [
  { id: 1, name: "Alice", total_score: 5.2, max_score: 6.0, failed_tests: ["test_model"], feedback: "Good job" },
  { id: 2, name: "Bob", total_score: 3.9, max_score: 6.0, failed_tests: ["test_controller"], feedback: "Check controllers" }
]
RubyTestStudentGrader::ClassReporter.new(students, course_name: "IIC2143", output_dir: "public/reports").generate_all

RubyTestStudentGrader::Similarity.jaccard(code_a, code_b, k: 5) # => 0.0..1.0
