Where appropriate prefer the more concise Regexp#match?, String#include?,
String#start_with?, and String#end_with?

Those are assertions that I really do miss from the standard
`ActiveSupport::TestCase`. Think of those as a more general version of
`assert_difference` and `assert_no_difference` (those can be implemented
by assert_changes, should this change be accepted).
Why do we need those? They are useful when you want to check a
side-effect of an operation. `assert_difference` do cover a really
common case, but we `assert_changes` gives us more control. Having a
global error flag? You can test it easily with `assert_changes`. In
fact, you can be really specific about the initial state and the
terminal one.
```ruby
error = Error.new(:bad)
assert_changes -> { Error.current }, from: nil, to: error do
expected_bad_operation
end
```
`assert_changes` follows `assert_difference` and a string can be given
for evaluation as well.
```ruby
error = Error.new(:bad)
assert_changes 'Error.current', from: nil, to: error do
expected_bad_operation
end
```
Check out the test cases if you wanna see more examples.

as this can lead to confusing time stubbing.
Instead of:
travel_to 2.days.from_now do
# 2 days from today
travel_to 3.days.from_now do
# 5 days from today
end
end
preferred way to achieve above is:
travel_to 2.days.from_now
# 2 days from today
travel_back
travel_to 5.days.from_now
# 5 days from today
Closes #24690
Fixes #24689

Time.new is a Ruby method that uses system timezone. Traveling in time
using it is a recipe for confusion. Instead, Time.zone.local should
be used since it uses the Rails timezone.

The line filter parsing added to ActiveSupport::TestCase is only half the story
to enable line filtering. The other half, of adding the patterns to the options,
is done in the Minitest plugin that Railties has.
Thus it makes more sense to have the filter in Railties with the other half and
all the line filtering tests.
Move the filter and extend Active Support in an initializer, so that when users
or `rails/all.rb` require `rails/test_unit/railtie` we can still filter by line.

Add tests for ActiveSupport::Deprecation.deprecate_methods
Modify ActiveSupport::Testing::Deprecation to allow a custom deprecator
Leverage ActiveSupport::Testing::Deprecation assert_deprecated
Update documentation for ActiveSupport::Deprecation.deprecate_methods
Use cases:
Using the default deprecator => "removed from Rails X.Y"
Passing a custom deprecator in the options hash => "removed from MyGem next-release"
Deprecating methods directly from custom deprecator => "removed from MyGem next-release"

With this we can perform new assertions on the returned value without having
to cache it with an outer variable or wrapping all subsequent assertions inside
the `assert_difference` block.
Before:
```
post = nil
assert_difference -> { Post.count }, 1 do
Post.create
end
assert_predicate post, :persisted?
```
Now:
```
post = assert_difference -> { Post.count } do
Post.create
end
assert_predicate post, :persisted?
```

Add `assert_called` and `assert_not_called` to boil down the boilerplate we need to write
to assert methods are called certain number of times.

This also adds free mix and matching of directories, files and lines filters.
Like so:
bin/rails test models/post_test.rb test/integration models/person_test.rb:26
You can also mix in a traditional Minitest filter:
bin/rails test test/integration -n /check_it_out/

Extracted silence_stream method to new module in activesupport/testing
|

- Added include for the same in ActiveSupport::Test.
- Removed occurrences of silence_stream being used elsewhere.
- Reordered activesupport testcase requires alphabetically.
- Removed require of silence stream from test_case
- Moved quietly method to stream helper
- Moved capture output to stream helper module and setup requires for the same elsewhere

Performance optimization: `yield` with an implicit `block` is faster than `block.call`.
See http://youtu.be/fGFM_UrSp70?t=10m35s and the following benchmark:
```ruby
require 'benchmark/ips'
def fast
yield
end
def slow(&block)
block.call
end
Benchmark.ips do |x|
x.report('fast') { fast{} }
x.report('slow') { slow{} }
end
# => fast 154095 i/100ms
# => slow 71454 i/100ms
# =>
# => fast 7511067.8 (±5.0%) i/s - 37445085 in 4.999660s
# => slow 1227576.9 (±6.8%) i/s - 6145044 in 5.028356s

The Logger by default includes a guard which checks for the
logging level. By removing the custom logging guards, we can decouple
the logging guard from the logging action to be done.
This also follows the good practice listed on http://guides.rubyonrails.org/debugging_rails_applications.html#impact-of-logs-on-performance.

As there is no forking on JRuby, we need to spawn sub-processes to make
the tests run in isolation.
Previously, we were defining globally env variables and running the test
file through backticks and delete these variables once the test ran.
Now, we simply rely on IO.popen as this is cross-platform and the env
variables are available during the child-process execution only so there
are no race conditions.

Rails applications are expected to be always aware of the application
time zone.
To be consistent with that contract, we have to assume that a bare
date passed to time helpers is a date in the application time zone,
not in the system time zone. The system time zone is irrelevant, we
should totally ignore it.
For example,
travel_to user.birth_date + 40.years
should make that user be 40th years old regardless of the system
time zone. Without this patch that may not be true.

This behavior is only work out-of-box with minitest and also add a
downside to run after each test case, even if we don't used the travel
or travel_to methods
