Marica Odagaki 613f0b2559 Upgrade to Jasmine 3 (#4226)
* process.exit() only exist in a node.js environment

* updateInterval has been removed from upstream

From upstream commit:
b6eb9a4d5e

* Update Jasmine to 3.4.0

* Reuse the evalInContext helper

* Fix expected parse result to match the actual result

* 'describe' cannot be nested inside 'it' blocks

Jasmine started to explicitly raise an error in these cases since:
https://github.com/jasmine/jasmine/pull/1411

* Be consistent about how to refer to library files

* Update link to Jasmine's official website

// The `global` property is needed in two places:
// 1. jasmine-core/node_boot.js: extends the global object with jasmine interface.
// 2. jasmine-core/jasmine.js: when it's loaded, if it determines that it's
// running in a commonjs environment and `global` is undefined, it will set
// `jasmineGlobal`, its internal reference to the global object, to {},
// which is not what we want. Alternatively, the `jasmine.getEnv()` API allows
// you to pass in a `global` object, but the boot scripts we use don't allow
// the caller to customize the `.getEnv()` call. We'd rather use the boot scripts
// as-is than duplicating them in order to do minor tweaks.
//
// We need this `$tw.browser ?` conditional because:
// 1. In a browser environment, 'jasmine-core/jasmine.js' calls `setTimeout` like
// `setTimeout.apply(jasmineGlobal, ...)`; the browser throws an "illegal invocation"
// unless `jasmineGlobal` is the right context object, which is `window`.
// 2. In Node.js, there is no `window` object.
// Further more, we don't have access to the `global` object when this code
// is executed, so we use the `context` object instead.
