So the GNU coreutils should be avaialable on all linux based systems (please correct me if I am wrong here). If you do not know what system you are using you may not be able to directly jump to one of the examples above, hence this may be your first port of call. `$ uname -a On my system this giv...

The simplest form of wait statement is simply: wait; Whenever a process executes this it is suspended forever. The simulation scheduler will never resume it again. Example: signal end_of_simulation: boolean := false; ... process begin clock <= '0'; wait for 500 ps; clock <= '1...

A process with a sensitivity list cannot also contain wait statements. It is equivalent to the same process, without a sensitivity list and with one more last statement which is: wait on <sensitivity_list>; Example: process(clock, reset) begin if reset = '1' then q &l...

It is possible to omit the on <sensitivity_list> and the for <timeout> clauses, like in: wait until CONDITION; which is equivalent to: wait on LIST until CONDITION; where LIST is the list of all signals that appear in CONDITION. It is also equivalent to: loop ...

Nightwatch supports creating custom commands that can simulating keystrokes, mouse clicks, and other inputs. A custom command can be chained with other Nightwatch commands, like so: module.exports = { "Login App" : function (client) { client .url("http://localhost:300...

Since Nightwatch has access to the browser console, it's possible to inspect client side objects using the .execute() API. In the following example, we're checking the Session object for a particular session variable. First, we begin by creating the file ./tests/nightwatch/api/meteor/checkSession...

To upload a file, you'll first need to create a /data directory, and add the file you'll want to upload. tests/nightwatch/data/IM-0001-1001.dcm Your form will need an input with type of file. (Some people don't like the styling options this input provides; and a common pattern is to make this in...

Page Objects are similar to Custom Commands; except they are collections of custom commands that are associated with a specific UI component. This works extremely well with modern component based design, such as in React. module.exports = { url: 'http://localhost:3000/login', commands: [{ ...
