glob-file-split

This glob-file-split will split a glob pattern of files into a given number of chunks (splits) and return the files as a comma separated string for a given index.

This is ideal for splitting test files across multiple workers for parallel execution.

Examples:

    $ glob-file-split --splits 2 --index 0 --pattern './tests/*.js'
    ./tests/1.js,./tests/2.js,./tests/3.js

    $ glob-file-split -s 2 -i 1 -p './tests/*.js'
    ./tests/4.js,./tests/5.js

Example using to split test execution:

Worker 1:

    $ yarn test --spec $(glob-file-split -s 2 -i 0 -p './**/*.feature')
    cypress run --spec ./cypress/integration/1.feature,./cypress/integration/2.feature,./cypress/integration/3.feature

Worker 2:

    $ yarn test --spec $(glob-file-split -s 2 -i 1 -p './**/*.feature')
    cypress run --spec ./cypress/integration/4.feature,./cypress/integration/5.feature

Parameters

| flag | shorthand | accepts | example | | -------------- | --------- | ------- | -------------------- | | --pattern | -p | string | './tests/*.feature' | | --index | -i | number | 0 | | --splits | -s | string | 5 | | --deleteOthers | -d | boolean | -d |
