Python Test Case Generator that can generate a test case from Python expression.
This tool allows you to generate a test case by writing Python expressions directly.
$ pip install python-testcase-generator
By calling python-testcase-generator (or pytcgen) with no parameters, a test case is generated from stdin
and output as stdout.
$ echo "[i**2 for i in range(9)]" | python-testcase-generator 0 1 4 9 16 25 36 49 64
To generate a test case from a file, you can specify input file path with -i parameter.
For example, to generate a test case from the file below:
$ cat test.txt 1 2 3 "a" ["b", "c"] [1,2,3]*2 # comment 10*"a" 10**9+7 % # You can write expressions including space by using backquote (`). % # It does not mean repr() in Python 2. (special specification in this tool) `"b" * 15` `1 + 2 * 3` % # You can use Python statement by beginning a line with percent sign (%). % # Any character is not output in Python statement except print statement. % x = [1, 2]; y = [9, 3, 4, "d"] x[0] x y*2 {4, x[1], 6} % # import and use library % import random % A=[random.randint(1, 10) for i in range(3)] A % # to_s function (builtin function in this tool) % B=[[1,2,3],[4,5],[6,[7,8]]] to_s(A, "\n") to_s(B, ["\n","-"])
You can specify input file path as follows:
$ python-testcase-generator -i test.txt 1 2 3 a b c 1 2 3 1 2 3 aaaaaaaaaa 1000000007 bbbbbbbbbbbbbbb 7 1 1 2 9 3 4 d 9 3 4 d 2 4 6 7 5 1 7 5 1 1-2-3 4-5 6-7 8
Also, to write generated a test case to a file, specify output file path with -o parameter.
$ python-testcase-generator -i test.txt -o output.txt
