/*
* Declaratively-defined tests for views for all database commands. This file contains a map of test
* definitions as well as code to run them.
*
* The example test
*
* {
* command: {insert: "view", documents: [{x: 1}]},
* expectFailure: true
* }
*
* invokes runCommand with `command` and expects it to fail with an error code specific to views.
* A test can be an array of subtests as well.
*
* Each test or subtest takes the following options:
*
* command
* The command object to pass to db.runCommand(). Each command can assume that there exists a
* view named "view", built on top of a collection named "collection". A command can also be a
* function that takes a db handle as argument and handles pass/failure checking internally.
*
* isAdminCommand
* If true, will execute 'command' against the admin db.
*
* skip
* A string that, if present, causes the test runner to skip running this command altogether.
* The value should be the reason why the test is being skipped. (There is a predefined
* selection of commonly-used reasons below.)
*
* expectFailure
* If true, assert that the command fails. Otherwise, all commands are expected to succeed.
*
* expectedErrorCode
* When 'expectFailure' is true, specifies the error code expected. Defaults to
* 'CommandNotSupportedOnView' when not specified. Set to 'null' when expecting an error
* without an error code field.
*
* setup
* A function that will be run before the command is executed. It takes a handle to the 'test'
* database as its single argument.
*
* teardown
* A function that will be run after the command is executed. It takes a handle to the 'test'
* database as its single argument.
*
* skipSharded
* If true, do not run this command on a mongos.
*
* skipStandalone
* If true, do not run this command on a standalone mongod.
