Test Data Generator

Test Data Generator is a helper for generating test data for coding problems

Features

• Easy to use: use simple custom script to generate test data
• Save time: no longer to write source for test data in other complex language
• Fast: compile the script to TD assambly (test-data assembly) which helps generating multiple file
• Convenient: create answer file and input file at the same time

Installation

Download Binary

There is no need to install anything on your computer. Just download the binary file from the release

Build from Source

git clone https://github.com/revival0728/test-data-generator.git
cd test-data-generator
cargo build --release

Usage

Compile Script

tdg -c [File Path]

Run Compiled Script

tdg -e [Compiled File Path] [-n [Generate File Count:default=1]] 
[--filename-format [Format:default=origin_file_name]] 
[--create-answer [Answer Execution Command:default=""]] 
[--id-base [Generate ID Starting Number:default=0]]
[--output-dir [Output Directory for Test Data:default="."]]

Argument Notice

• -c: [File Path] should end with .tds
• -e: [Compiled File Path] should end with .tdc
• -n: to set this argument, you also have to set argument --filename-format
• --filename-format: needs to contain * in parameter. represents the length of file ID e.g. "test_**"

Script Grammer

Variable

Each "random statement" in the script is Variable

A Variable can be define as ( Material ; Type ; Quantity ; End Char )

A Material can be any character or macro provided

A Type can be int, float, string and =, which = means auto in other language

A Quantity can be a positive integer, which means the quantity of test data that this Variable will generate

A End Char can be any character, which will add between each generated test data in this Variable

Material, Type and Quantity are necessary attributes in one Variable

Notice that Material and End Char cannot be " ", "\", "(", "), ";", "\n" if you want to add these charater please use the macro provided

Material

BEGIN and END are special Material which doesn't belong to any type and cannot add to the Variable that contains other Material

BEGIN doesn't required Type and END doesn't required Type and Quantity

The program will keep repeating between BEGIN and END Quantity(in BEGIN) times

All the other Variable must between at least one BEGIN and END

A int Material can be define as [L]..[R]([L, R])

A float Material can be define as [L]..[R]:.[P].f([L, R] with precision [P])

If you want to remove the Material except for adding it, add "\" before the Material

Macro

macro can be put in Material, below is the list of all macro

• UPC: upper cases
• LOC: lower cases
• SML: symbols
• ALC: all characters (UPC + LOC + SML)
• SPACE: " "
• BSL: "\"
• LSB: "("
• RSB: ")"
• SEMI: ";"

Example

Each example file is in test_file folder

test1.tds

script

(BEGIN;; 1)(1..10 ; int ; 10)(END)

generate

25364241089

test2.tds

script

(BEGIN;; 3)

abc
 
(1..10 3..19; = =; 3) (UPC SPACE LOC; = = =; 10)
(END)

generate

abc
 
6714 VUJvsu Esl


abc

abc
 
745 vLYUkbAZdm

test3.tds

script

(BEGIN;; 1)(ALC \abcdefg ; = string ; 8 ; *)
(1..100 \25..75 ; = int ; 11; SPACE)
(1..100:.4f \25..75:.4f ; = float ; 15; SPACE)(END)

generate
