1 Introduction
The Subplot library files provides scenario steps and their
implementations for managing files on the file system during tests.
The library consists of a bindings file lib/files.yaml and
implementations in Python in lib/files.py or in Rust within the
subplotlib crate.
This document explains the acceptance criteria for the library and how
they're verified. It uses the steps and functions from the files
library.
2 Create on-disk files from embedded files
Subplot allows the source document to embed test files, and the
files library provides steps to create real, on-disk files from
the embedded files.
given file hello.txt
then file hello.txt exists
then file hello.txt contains "hello, world"
then file other.txt does not exist
given file other.txt from hello.txt
then file other.txt exists
then files hello.txt and other.txt match
then only files hello.txt, other.txt exist
hello, world
These steps create files and manage their metadata.
given file hello.txt
when I remember metadata for file hello.txt
then file hello.txt has same metadata as before
when I write "yo" to file hello.txt
then file hello.txt has different metadata from before
4 File modification time
These steps manipulate and test file modification times.
given file foo.dat has modification time 1970-01-02 03:04:05
then file foo.dat has a very old modification time
when I touch file foo.dat
then file foo.dat has a very recent modification time
5 File contents
These steps verify contents of files.
given file hello.txt
then file hello.txt contains "hello, world"
then file hello.txt doesn't contain "hello, sailor"
then file hello.txt matches regex "hello, .*"
then file hello.txt matches regex /hello, .*/
6 Directories
There are also a large number of directory based steps and some directory
based behaviour available in creating files which are available in the files
library.
given a directory first
then directory first exists
then directory first is empty
then directory second does not exist
when I remove directory first
then directory first does not exist
when I create directory second
then directory second exists
then directory second is empty
given file second/third/hello.txt from hello.txt
then directory second is not empty
then directory second/third exists
then directory second/third is not empty
when I remove directory second
then directory second does not exist
