This is a technical task for Byte. The code provided provides modules to validate data and a checksum
You'll need the following installed locally to run the install and run the tests within this project:
- Node 12.x
- NPM 6.x
NPM and Node are required to run this. Run the following commands
npm i
npm testOutput should be as follows:
PASS src/validateChecksum.test.ts
validateChecksum
NUMBER_COMPARE_GENERATOR
✓ a value of 1122 and a checksum of 3 should return true (1 ms)
✓ a value of 1111 and a checksum of 4 should return true (1 ms)
✓ a value of 91212129 and a checksum of 9 should return true
✓ 01-general.txt value and a checksum of 1393 should return true (1 ms)
✓ a value of 91212129 and an invalid checksum should return false
TSV_GENERATOR
✓ a row of 5 1 9 5 should validate a checksum of 8 to true (1 ms)
✓ a row of 7 5 3 should validate the checksum of 4 to true
✓ a row of 2 4 6 8 should validate the checksum of 6 to true
✓ the tsv file 02-general.tsv value and checksum of 32121 should return true (1 ms)
✓ a row of 0 5 7 9 with an invalid checksum should return false
PASS src/generateChecksum.test.ts
generateChecksum
NUMBER_COMPARE_GENERATOR
✓ a value of 1122 should generate a checksum of 3 (1 ms)
✓ a value of 1111 should generate a checksum of 4
✓ a value of 91212129 should generate a checksum of 9
✓ the value in 01-general.txt value should generate a checksum of 1393 (1 ms)
✓ expect an invalid generator version to throw an error (9 ms)
TSV_GENERATOR
✓ a row of 5 1 9 5 should generate a checksum of 8
✓ a row of 7 5 3 should generate a checksum of 4
✓ a row of 2 4 6 8 should generate a checksum of 6 (1 ms)
✓ the tsv file 02-general.tsv value should generate a checksum of 32121
