pictts

PICT clone by TypeScript.

Example

const pictts = require('pictts');
const pict = new pictts.Parser(
    `
Type:           Primary, Logical, Single, Span, Stripe, Mirror, RAID-5
Size:           10, 100, 500, 1000, 5000, 10000, 40000
Format method:  quick, slow
File system:    FAT, FAT32, NTFS
Cluster size:   512, 1024, 2048, 4096, 8192, 16384, 32768, 65536
Compression:    on, off

IF [File system] = "FAT"   THEN [Size] <= 4096 ;
IF [File system] = "FAT32" THEN [Size] <= 32000 ;
`
).parse();
const testCases = pict.testCases();
testCases.toString();

try it on RunKit.

Usage

Parse and Generate test cases

const pictts = require('pictts');
const pict = new pictts.Parser(
    `
A:A1,A2
B:B1,B2
C:C1,C2
`
).parse();
const testCases = pict.testCases();
testCases.toString();

Result

A	B	C
A2	B1	C1
A1	B2	C1
A2	B2	C2
A1	B1	C2
A1	B2	C2

Change order of combinations

If you want to triplewise test case like /o:3.

const pictts = require('pictts');
const pict = new pictts.Parser(
    `
A:A1,A2
B:B1,B2
C:C1,C2
`
).parse();
pict.setFactorCount(3); // All combinations between 3 factors
const testCases = pict.testCases();
testCases.toString();

Result

A	B	C
A2	B2	C1
A1	B2	C2
A2	B1	C2
A2	B1	C1
A1	B2	C1
A1	B1	C1
A2	B2	C2
A1	B1	C2

Change delimiter

Changing delimiter. Default is \t.

const pictts = require('pictts');
const pict = new pictts.Parser(
    `
A:A1,A2
B:B1,B2
C:C1,C2
`
).parse();
const testCases = pict.testCases();
testCases.toString('|'); // specify `|` as delimiter

Result

A|B|C
A2|B1|C1
A1|B2|C1
A2|B2|C2
A1|B1|C2
A1|B2|C2

Optimizing result

Number of test cases by PICT depends on random seed. It means changing seed changes number of test.

When power parameters increases, pictts repeat generating test cases and search less number of test cases.

const pictts = require('pictts');
const pict = new pictts.Parser(
    `
A:A1,A2
B:B1,B2
C:C1,C2
`
).parse();
pict.setPower(100); // specify repeat count
const testCases = pict.testCases();
testCases.toString();
