Good tests encode the developer's intention, they don't only lock in the test's behavior without editorialization of what's important and why. Snapshot tests lack (or at least, fail to encourage) expressing the author's intent as to what the code does (much less why)

I should also add that I'm in favor of relying more heavily on integration testing. When you do this, you need to unit test fewer of your simple components and wind up only having to unit test edge cases for components (which can mock all they want).

was browsing through some journal articles and stumbled across John Milton’s annotated copy of Shakespeare’s first folio

Often, if you are writing a test that amounts to “it does what it does”, or “it does exactly this, which happens to be duplicated in the application code”, then the test is either unnecessary or too broad.

Here are three rules of thumb I use to determine that something is not worth testing:Will the test have to duplicate exactly the application code? This will make it brittle.Will making assertions in the test duplicate any behavior that is already covered by (and the responsibility of) library code?From an outsider’s perspective, is this detail important, or is it only an internal concern? Can the effect of this internal detail be described using only the component’s public API?

I had to upgrade my other project from Webpack 2 / Angular 5 to Webpack 4/Angular 7 and it was a complete nightmare! I lost a ton of hours and can't really justify charging my client for the weeks worth of time to figure it out.

But the machete bears an unusual character. It’s possible to conceive of it as a weapon, yes, but it’s also very much a tool—not altogether different from, say, a shovel. It’s possible that Wilson is just a stunted adolescent who never grew out of buying switchblades and throwing stars when the carnival comes to town, but the ease with which “tool” becomes “weapon” in the eyes of the law is remarkable.

Machete

“full size” machete.

the machete has a special place in the labor history of Florida, where for three and a half centuries slaves and wageworkers cut sugarcane in the fields by hand. Indeed, machetes are unique to the extent that they have always been used for both purposes—and not just as a plot device in horror flicks, either.

I quickly realized from the descriptions that a machete was essentially the same thing as a “corn knife.”

He calls for more thoughtful engagement with the notion not so much of making things, but of fixing them, repurposing them in their diminishment and dismantlement—not of making new, but of making do, and of thereby engaging what he calls ‘an ethics of mutual care’—with each other, the world around us, and with the (quite literal) objects of our affection (Jackson, 2013, p. 231). This is a source, he says, of ‘resilience and hope’ and it’s a way of being in space and time that has deep feminist roots (Jackson, 2013, p. 237).

Null values can thus quickly spread through a database, rendering everything they touch indeterminate

until black women on social media began calling out the press for ignoring the story. Many reached for one word — ‘‘erasure’’ — for what they felt was happening. ‘‘Not covering the #Holtzclaw verdict is erasing black women’s lives from notice,’’ one woman tweeted. ‘‘ERASURE IS VIOLENCE.’’ Deborah Douglas, writing for Ebony magazine, argued that not reporting on the case ‘‘continues the erasure of black women from the national conversation on race, police brutality and the right to safety.’’

Handy javascript constructor tip: you can include a this instanceof Widget check like above to let people consume your module with new Widget or Widget(). It's nice because it hides an implementation detail from your API and you still get the performance benefits and indentation wins of using prototypes.
