App Channel Tests 
Basic Broadcast
| App | Step | Details |
|---|---|---|
| A | 1.Retrieve Channel | Retrieve a Channel object representing an 'App' channel called test-channel using: const testChannel = await fdc3.getOrCreateChannel("test-channel") |
| A | 2.Add Context Listener | Add an untyped context listener to the channel, using: await testChannel.addContextListener(null, handler) testChannel.addContextListener(null, handler) |
| B | 3.Retrieve Channel | Retrieve a Channel object representing the same 'App' channel A did (test-channel) |
| B | 4.Broadcast | Broadcast an fdc3.instrument Context to the channel with: testChannel.broadcast(<fdc3.instrument context>) |
| A | 5.Receive Context | The handler added in step 2 will receive the instrument context. Ensure that the instrument received by A is identical to that sent by B. |
ACBasicUsage1Perform above test.
Current Context
| App | Step | Details |
|---|---|---|
| B | 1.Retrieve Channel | Retrieve a Channel object representing an 'App' channel called test-channel using: const testChannel = await fdc3.getOrCreateChannel("test-channel") |
| B | 2.Broadcast | Broadcast an fdc3.instrument to the channel using: testChannel.broadcast(<fdc3.instrument context>) |
| A | 3.Retrieve Channel | Retrieve a Channel object representing the same 'App' channel B did (test-channel) |
| A | 4.Retrieve Current Context | A gets the current context of the user channel. via: await testChannel.getCurrentContext() Ensure that the instrument received by A is identical to that sent by B |
ACBasicUsage2Perform above test
Filtered Context
| App | Step | Details |
|---|---|---|
| A | 1.Retrieve Channel | Retrieve a Channel object representing an 'App' channel called test-channel using: const testChannel = await fdc3.getOrCreateChannel("test-channel") |
| A | 2.Add Context Listener | Add an typed context listener for fdc3.instrument, using: await testChannel.addContextListener("fdc3.instrument", handler) testChannel.addContextListener("fdc3.instrument", handler) |
| B | 3.Retrieve Channel | Retrieve a Channel object representing the same 'App' channel A did (test-channel) |
| B | 4.Broadcast | B broadcasts both an fdc3.instrument context and an fdc3.contact context, using: testChannel.broadcast(<fdc3.instrument context>) testChannel.broadcast(<fdc3.contact context>) |
| A | 5.Receive Context | An fdc3.instrument context is received by the handler added in step 2. Ensure that the fdc3.instrument received by A is identical to that sent by B Ensure that the fdc3.contact context is NOT received. |
ACFilteredContext1: Perform above testACFilteredContext2: Perform above test, but add listeners for bothfdc3.instrumentandfdc3.contactin step2. Ensure that both context objects are received.ACFilteredContext3: Perform above test, except creating a different channel in app B. Check that you don't receive anything (as the channels don't match).ACFilteredContext4: Perform above test, except that after creating the channel A creates another channel with a further different channel id and adds a further context listener to it. Ensure that A is still able to receive context on the first channel (i.e. it is unaffected by the additional channel) and does NOT receive anything on the second channel.ACUnsubscribe: Perform above test, except that after creating the channel A thenunsubscribe()s the listener it added to the channel. Check that A does NOT receive anything.
App Channel History
| App | Step | Details |
|---|---|---|
| A | 1.Retrieve Channel | Retrieve a Channel object representing an 'App' channel called test-channel using: const testChannel = await fdc3.getOrCreateChannel("test-channel") |
| B | 2.Retrieve Channel | Retrieve a Channel object representing the same 'App' channel A did (test-channel) |
| B | 3.Broadcast | B broadcasts both the instrument context and a contact context, using: testChannel.broadcast(<fdc3.instrument context>) testChannel.broadcast(<fdc3.contact context>) |
| A | 4.Add Context Listener | A adds a context listener to the channel after B has completed all its broadcasts, via: await testChannel.addContextListener("fdc3.instrument", handler) testChannel.addContextListener("fdc3.instrument", handler) Ensure that A does NOT receive any context via these listeners (past context is only retrieved via a getCurrentContext() call on App channels). |
| A | 5.Retrieve Current Context | A is able to retrieve the most recent context of each context type from the Channel via: const instrument = await testChannel.getCurrentContext('fdc3.instrument')const instrument = await testChannel.getCurrentContext('fdc3.contact')Ensure that both contexts retreived by A are identical to those sent by B |
ACContextHistoryTyped: Perform above test.ACContextHistoryMultiple: B Broadcasts multiple history items of both types. Ensure that only the last version of each type is received by A.ACContextHistoryLast: In step 5. A retrieves the untyped current context of the channel viaconst currentContext = await testChannel.getCurrentContext(). Ensure that A receives only the very last broadcast context item of any type.
