with-tmp-dir

Little test helper that wraps a test function and provides it a temporary directory. The directory gets automatically removed after the test has run. In case the test failed (threw or return a rejected promise), the directory stays in place and its path gets console.loged so you can investigate.

Usage

const withTmpDir = require('with-tmp-dir');
 
it('Tests something amazing', withTmpDir((path) => {
    // Do some testing in the temporary directory
});

Configuring created directory

You can control where the directory will get created and what name it will have by setting the appropriate tmp-promise options:

• for all withTmpDir call by setting properties on the withTmpDir function
• for a specific call by providing an Object as 2nd argument (its properties will be merged with the default ones)
