From c04c1d73b30979d04d94398309ee47643ede0af4 Mon Sep 17 00:00:00 2001 From: David da Silva Date: Mon, 23 May 2016 07:01:41 +0200 Subject: [PATCH] Make CI run browser tests (#2231) * Initial prep for browser tests in CI - :arrow_up: browserify@13.0.0 Some fixes that we didn't have were required. - :bug: Fix browser not being able to require describe/it `support/browser-entry.js` was removing the listener that is in charge of keeping `Mocha.describe/it/suite` etc up-to-date. That listener is now added everytime a `ui` is set up. - Correct isatty for browser * Travis + SauceLabs + Karma setup (first pass) - add sauce connect - prepare to use karma on saucelabs; fix potential windows problems - rewrite `scripts/ensure-compatible-npm.sh` in JS - detect travis node 0.8 env; just upgrade if found - symlink `mocha` to itself for `karma-mocha` - if explicit `--production` flag is present, skip this - don't know how to skip this part if `mocha` is a devDep of some other package - use phantomjs@1.9.19; don't try to install npm@3 - browser tests with karma & phantom - move `support/browser-entry.js` to `browser-entry.js` to keep paths sane - `karma.conf.js` loads data out of `.karma.conf.js` - we have a "main" browser suite - then we have suites for each interface - each suite is a single run of Karma - each suite is executed by the `Makefile` - build `./mocha.js` upon test execution for `karma-mocha` to use - bonus: 3rd-party browserification should theoretically now be possible as per the `./index.js` entry in `package.json`'s `browser` field - add dev deps for karma - test changes: - split `lookupFiles` test into its own file so we can ignore it in Karma - fix broken `test/acceptance/throw.js` for browser - fix `test/acceptance/utils.js`'s `type` tests for PhantomJS - try to reduce build matrix - fix missing targets - fix infinite loop in Makefile - downgrade phantomjs to 1.9.8 - remove some cruft from karma config; try to add sauce labs - try again w/ the saucelabs - typo - remove karma-source-map-support as it's a no-go on IE8 - Require up-to-date mocha.js for any browser tests - Make CI rebuild mocha.js. Make won't rebuild when just checked out by CI because timestamps on source and mocha.js are the same. We could use a script to set the timestamps to the commit time, but it still wouldn't work if mocha.js were committed along with other changes that hadn't been built into it. Which shouldn't happen anyway -- but then again, the point of CI is to see what commits change, it's usually going to need to rebuild mocha.js if it's working right, so it's not going to hurt much to rebuild it every time even on the few times it doesn't need to. * fix IE8 compatibility for browser tests - Avoid `Array.prototype.map` in test - Workaround for missing `Object.create` - Use a shim for `Date.prototype.toISOString` - Use simple number math instead of array indexing for interface tests - Use `expect` instead of `should` - Avoid builtin function in stringify test (A quick check revealed that stringify does not treat toString specially anyway, and IE8 ignores the toString assigned to the object, so use a different property name) - Use `karma-expect` for automatic browser tests - Remove `karma-should` * Travis + SauceLabs + Karma setup (second pass) - add note about exporting `global` in `browser-entry.js` - remove too-short timeout for "throw" unit tests (because SauceLabs) - revert modification to `isatty()` function of `lib/browser/tty.js` - switch reporter to `karma-spec-reporter` - use custom `karma-no-mocha` package - fixtures in `test/browser-fixtures/` - use single `karma.conf.js` --- .travis.yml | 37 +- CHANGELOG.md | 8 + Makefile | 50 +- support/browser-entry.js => browser-entry.js | 7 +- karma.conf.js | 97 + lib/mocha.js | 33 +- lib/utils.js | 10

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output.

Sometimes it's called a "filter", +// but that's not a great name for it, since that implies a thing where +// some bits pass through, and others are simply ignored. (That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. - // 1110XXXX - if (i <= 2 && c >> 4 == 0x0E) { - this.charLength = 3; - break; - } +'use strict'; - // 11110XXX - if (i <= 3 && c >> 3 == 0x1E) { - this.charLength = 4; - break; - } - } - this.charReceived = i; -}; +module.exports = Transform; -StringDecoder.prototype.end = function(buffer) { - var res = ''; - if (buffer && buffer.length) - res = this.write(buffer); +var Duplex = require('./_stream_duplex'); - if (this.charReceived) { - var cr = this.charReceived; - var buf = this.charBuffer; - var enc = this.encoding; - res += buf.slice(0, cr).toString(enc); - } +/**/ +var util = require('core-util-is'); +util.inherits = require('inherits'); +/**/ - return res; -}; +util.inherits(Transform, Duplex); -function passThroughWrite(buffer) { - return buffer.toString(this.encoding); -} +function TransformState(stream) { + this.afterTransform = function (er, data) { + return afterTransform(stream, er, data); + }; -function utf16DetectIncompleteChar(buffer) { - this.charReceived = buffer.length % 2; - this.charLength = this.charReceived ? 2 : 0; + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; + this.writeencoding = null; } -function base64DetectIncompleteChar(buffer) { - this.charReceived = buffer.length % 3; - this.charLength = this.charReceived ? 3 : 0; -} +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; -},{"buffer":43}],65:[function(require,module,exports){ -module.exports = function isBuffer(arg) { - return arg && typeof arg === 'object' - && typeof arg.copy === 'function' - && typeof arg.fill === 'function' - && typeof arg.readUInt8 === 'function'; + var cb = ts.writecb; + + if (!cb) return stream.emit('error', new Error('no writecb in Transform class')); + + ts.writechunk = null; + ts.writecb = null; + + if (data !== null && data !== undefined) stream.push(data); + + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } } -},{}],66:[function(require,module,exports){ -(function (process,global){ -// Copyright Joyent, Inc. and other Node contributors. -// -// Permission is hereby granted, free of charge, to any person obtaining a -// copy of this software and associated documentation files (the -// "Software"), to deal in the Software without restriction, including -// without limitation the rights to use, copy, modify, merge, publish, -// distribute, sublicense, and/or sell copies of the Software, and to permit -// persons to whom the Software is furnished to do so, subject to the -// following conditions: -// -// The above copyright notice and this permission notice shall be included -// in all copies or substantial portions of the Software. -// -// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS -// OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF -// MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
