You can run the task using ruby main.rb in the project folder. This will read the file at spec/support/files/backup_log.txt, output the failed deletions to output.txt (in the project folder), parse from the same output.txt and print out the number of successful vs unsuccessful deletions in the console.
You can run the test suite with rspec from within the project folder.
This includes a test for each of the two tasks, located in:
spec/lib/task/backup_deleter_spec.rbspec/lib/task/failed_backup_deletion_reporter_spec.rb
After running rspec, the coverage report will be visible at coverage/index.html.
Some assumptions were made over the course of developing this solution. They are listed below:
The deletion log was described as having the following format:
ID Created at Status Code ErrorDescription
a680 2019-07-10 00:08:02 +0000 Removed 200
a181 2019-07-10 00:08:02 +0000 Error 500 "{error: 'invalid ID' }"
Since the intended spacing isn't obvious, I've assumed it to look like this:
ID Created at Status Code ErrorDescription
a680 2019-07-10 00:08:02 +0000 Removed 200
a181 2019-07-10 00:08:02 +0000 Error 500 "{error: 'invalid ID' }"
i.e. one space between words in the same heading, and two spaces for delimiting. I've also assumed 'Removed 200' and 'Error 500' are status codes, and not a 'status' and a 'code'.
The log file writer will only add headings to an empty or non-existent file, and for any existing files with content, it will simply append the lines.
Therefore, if running on the same data multiple times, the log will contain duplicate lines. I didn't have time to add more complex handling around this, so I left it for now.
Write a script that will parse a file with following file structure (2 spaces row delimiter):
ID Created at Status Size Database
a810 2019-07-10 00:08:02 +0000 Completed 2019-07-10 00:18:53 +0000 482.43MB DATABASE
a179 2019-07-09 00:06:19 +0000 Completed 2019-07-09 00:23:42 +0000 480.99MB DATABASE
a278 2019-07-08 00:06:19 +0000 Completed 2019-07-08 00:16:04 +0000 479.59MB DATABASE
a827 2019-07-07 00:08:02 +0000 Completed 2019-07-07 00:18:43 +0000 481.75MB DATABASE
You have to extract IDs of backups that were created more than 30 days ago.
Next you have to send the IDs (one by one) to the API endpoint `PUT https://example.com/remove-backup?backup_id=#{ID}`.
Correct API response status is 200, if it returns something else you also have to store the response body in the file with following format:
ID Created at Status Code ErrorDescription
a680 2019-07-10 00:08:02 +0000 Removed 200
a181 2019-07-10 00:08:02 +0000 Error 500 "{error: 'invalid ID' }"
Also write a script that will parse the events log text file and return the number of successful and failed backups deletions based on date range arguments provided.
Please include specs and provide an object oriented structure for the code.
