First, on Ubuntu to copy from the terminal use Ctrl+Shift+C, I don't know
whether this works on Windows but I am sure that if it does not then google
will tell you how to do it.

Second you cannot have 3 to 4 apps in one folder, you can have apps in
sub-folders of Sites, but you must run the server in the folder that is the
root of the app, that is the folder that contains the subfolders app,
config, db etc.  The server only runs one rails app at a time.

The default is that the database will be rolled back between tests. If
you look in test.log you will the rollbacks happening.

It is usually better to copy/paste this type of error rather than posting
an image. When running rails s you must be in the root folder of a rails
app, is there an app in c:\Sites?

I'm not sure but I think it rolls back changes (i.e., the transaction
each test is wrapped in) after each test.  Or that may be dependent on
what db and/or test framework you're using; I don't think it's even
possible with SQLite, but I usually use PostgreSQL.  Anyway, I've
usually used the database-cleaner gem
(https://github.com/DatabaseCleaner/database_cleaner) rather than rely
on whatever Rails chooses to do.  Check it out; there may be a
configuration that meets your needs.  Avdi Grimm also wrote a good
blog post on it long ago that I remember finding very helpful.

I only guess that it empties all tables after each test, but this is only

The important thing is that every test start from a *known state*.
The easiest state to achieve and reason about, is empty.  It also
forces you to be more explicit within your tests (or their
setup/before blocks) about any records you're adding in support of the
test.

But, if you want to start from a known *populated* state, that's a
pretty common approach too.

Either way, though, you need to clean up any changes each test makes.
With a populated start state, you can do each test in a transaction
and roll it back, which assumes you're using a DBMS that supports
that.  With an empty state, you can do that, *or* truncate the tables,
or various other options.

[Rails] Is the test database cleared after each test?

2016-12-02 Thread 'krfg' via Ruby on Rails: Talk 
Some of my tests would not pass if the test database was not cleared after 
the previous tests.
For instance my application, based on the Michael Hartl's tutorial, gives 
users the opportunity to create an association between two users.
The web interface is configured to use or not use Ajax.
There are usually two tests, one for Ajax and the other for standard html 
requests, and both of them check that the association between the same two 
users user1 and user2 was created by counting the number of user1 
relationships, that should be increased by 1. Now user1 could not create 
twice the same association with user2, unless that association was cleared 
after the first test. Is that so?
If this is Rails behaviour, which I only guess is such because I could not 
find documentation about it, I would rely on this for all my future tests.
In particular I would like to test a background job that populates my 
database by counting that the number of saved records (100) is correct as 
expected.
If the database is cleared after this test I could re run the test and I 
would still count 100 records.
If the database is not cleared, the second time I run the test I would 
count 200 records, so the test would fail.
