This is mainly intended to support jasmine-browser-runner, which will load
a script that configures the env in between the two boot files (boot0.js and
boot1.js). The single-file boot.js is retained for now but will be removed
in a future release.
The deprecation warning relies on Proxy, and won't work in environments
that don't have it. Among Jasmine's supported environments, that's Safari 9,
Safari 8, and all versions of IE.
* De-duplication now happens in core, not in reporters. This ensures that
the console doesn't get flooded.
* Stack traces are opt-out, not opt-in.
* The current runnable is not reported or logged for certain deprecations
where it's irrelevant.
* HtmlReporter shows stack traces in expandable widgets.
* Env#deprecated and Env#deprecatedOnceWithStack are merged.
This was a holdover from 1.x that should have been removed in 2.0,
but was missed. Suite is meant to be private, and almost none of
its methods can be safely called by user code.
Jasmine 1.x exposed Suite objects to user code as the `this` in describe
functions. That should have been removed in 2.0 but it was missed. It
will be removed in 4.0. This change adds a deprecation warning if anything
on a describe's `this` is accessed.
The deprecation warning relies on Proxy, and won't work in environments
that don't have it. Among Jasmine's supported environments, that's Safari 9,
Safari 8, and all versions of IE. In those browsers, a describe's `this`
will still be a Suite for now, but there will be no deprecation warnings.
Use setSpecProperty to attach key/value pairs to spec results that can be
picked up in specialized jasmine reporters. Example use-cases
include:
* Tagging specs with URLs or string-tokens referencing test-plan docs.
* Recording performance information for blocks of JS.
Similarly setSuiteProperty attaches key/value pairs to suite results
Previously, suite duration was always reported as 0 and spec duration
was always reported as null. Suites always used a no-op timer, and
specs set their result.duration after the result had already been sent
to reporters.
Fixes#1676.
* Include stack traces. This makes it easier to find the matcher that
needs to be updated, particularly when it comes from a library rather
than the user's own code.
* Show each deprecation only once unless `config.verboseDeprecations`
is set. Since matchers are often added in a global `beforeEach`, logging
deprecations every time can be overwhelming.
Custom object formatters allow users to customize how an object is
stringified in matcher failure messages. This can already be done by
adding a `jasmineToString` method to the objects in question. But
it's not always desirable or possible to do that, particularly when
objects of a given "type" do not inherit from a specific prototype.
For instance, suppose a web service returns a list of foos that are
deserialized from JSON, e.g.:
{ fooId: 42, /* more properties */ }
The only way to define `jasmineToString` on those is by writing code to
add it to each instance at runtime. But a custom object formatter can
recognize that the object it's looking at is a foo and format it
accordingly:
jasmine.addCustomObjectFormatter(function(obj) {
if (typeof obj.fooId !== 'number') {
return undefined;
}
return '[Foo with ID ' + obj.fooId + ']';
});
Unlike `jasmineToString`, custom object formatters are scoped to a
particular spec or suite and don't require any changes to the code
under test.
This will allow us to add support for custom object formatters, which
will be a per-runable resource like custom matchers, by injecting them
into the pretty-printer.
This makes it easier to write high quality matchers and asymmetric equality
testers, and is also a step toward supporting custom object formatters.
Previously, Jasmine passed custom object formatters as the second argument
to matcher factories and as and the second argument to asymmetric equality
testers' `asymmetricMatch` method. Matchers and asymmetric equality testers
were responsible for passing the custom object formatters to methods like
`matchersUtil#equals`:
function toEqual(util, customEqualityTesters) {
return {
compare: function(actual, expected) {
// ...
result.pass = util.equals(actual, expected, customEqualityTesters, diffBuilder);
And:
ArrayContaining.prototype.asymmetricMatch = function(other, customTesters) {
// ...
for (var i = 0; i < this.sample.length; i++) {
var item = this.sample[i];
if (!j$.matchersUtil.contains(other, item, customTesters)) {
return false;
}
}
With this change, that is no longer necessary. Matchers and asymmetric
equality testers can ignore the existence of custom equality testers and
still fully support them:
function toEqual(util) {
return {
compare: function(actual, expected) {
// ...
result.pass = util.equals(actual, expected, diffBuilder);
And:
ArrayContaining.prototype.asymmetricMatch = function(other, matchersUtil) {
// ...
for (var i = 0; i < this.sample.length; i++) {
var item = this.sample[i];
if (!matchersUtil.contains(other, item)) {
return false;
}
}
The old interfaces are still supported, for now, but will be deprecated
in a future commit and removed in the next major release after that.
In addition to making matchers and custom equality testers simpler,
this change sets the stage for adding support for custom object
formatters. Those will be architecturally similar to custom equality
testers, and by injecting a `MatchersUtil` instance everywhere we can
add them without requiring user code to pass them around as used to be
the case with custom object formatters.
It's very easy to forget to `await` or `return` the promise returned
from `expectAsync`. When that happens, the expectation failure will
occur after the spec or suite's result has been reported to reporters,
and the failure will typically not be shown to the user. This change
adds a top-level suite failure in that case, similar to the way we
report unhandled exceptions or promise rejections that occur after the
runable completes. Adding the error at the top level gives us the best
chance of getting in before the set of failures we add it to is sent
to reporters.
