Imagine you're testing code that makes a call to this interface, and you want to make sure your retry code is working. public interface DataStore { void save(Data data) throws IOException; } You could do something like this: public void saveChanges_Retries_WhenDataStoreCallFails() { ...

Adding dependcy To use a gruntplugin, you first need to add it as a dependency to your project. Let's use the jshint plugin as an example. npm install grunt-contrib-jshint --save-dev The --save-dev option is used to add the plugin in the package.json, this way the plugin is always installed aft...

REPEAT, will repeat itself forever unless you explicitly exit the loop: //Runs forever REPEAT: // Do stuff END. To exit the loop you can use the LEAVE keyword. With or without a label. Without a label LEAVE will always effect the current loop. With a name you can specify what loop to LEAV...

Let's explore an example Transaction search where we define a filter for a single transaction's internal ID: We've specified a filter to only show us results for the Transaction with the internal ID of 875; here is that Transaction: We can see it is a Sales Order with a single line item. Beca...

When we only want one result per transaction, that means we only want the Body, or Main Line, of each transaction. To accomplish this, there is a filter named "Main Line". By setting the Main Line filter to Yes in our search criteria, we are essentially saying "Only show me body-leve...

Recall that every transaction contains multiple sublists of data. Now that we can show only sublist data using Main Line, we can further refine our search results to specific sublist data. Most of the sublists included in Transaction results have a corresponding search filter to toggle whether they...

Recoding missing values Regularly, missing data isn't coded as NA in datasets. In SPSS for example, missing values are often represented by the value 99. num.vec <- c(1, 2, 3, 99, 5) num.vec ## [1] 1 2 3 99 5 It is possible to directly assign NA using subsetting num.vec[num.vec == 99]...
