Step 1: Open your TypeScript user defined snippets: Code > Preferences > User Snippets > (select TypeScript)
Step 2: Paste this block of JSON between the 2 brackets that are already there. Make sure it's not in the commented out text.
"Start a test 'it' block for a component": {
"prefix": "itc",
"body": [
"it('Should $1',",
" inject([${2:component}], (component: ${2:component}) => {",
" $4",
" }));"
],
"description": "Start at test 'it' block for a component"
},
"Start a test 'it' block for a service": {
"prefix": "its",
"body": [
"it('Should $1',",
" inject([${2:service}], (service: ${2:service}) => {",
" $4",
" }));"
],
"description": "Start at test 'it' block for a service"
}
Step 3: Profit
Use for testing. when testing a component, type itc
then tab. When testing a service, type its
then tab. Your cursor will automatically be placed in the string to write the 'it' portion of the spec. When you're done completing the string, press tab to advance to the next section (which is the name of the component or service you are testing) It will select both of these so you can edit them at the same time. Finally press tab a third time to advance to writing the actual spec.
