Gem Version

Name

grntest

Description

Grntest is a testing framework for Groonga. You can write a test for Groonga by writing Groonga commands and expected result.

Install

% gem install grntest

Basic usage

Write a test script that extension is .test. Here is a sample test script select.test:

table_create Users TABLE_HASH_KEY ShortText

load --table Users
[
{"_key": "Alice"},
{"_key": "Bob"}
]

select Users --query '_key:Alice'

Run grntest with select.test as command line argument:

% grntest select.test
N
================================================================================
.
  select                                                   0.3866s [not checked]
================================================================================
table_create Users TABLE_HASH_KEY ShortText
[[0,0.0,0.0],true]
load --table Users
[
{"_key": "Alice"},
{"_key": "Bob"}
]
[[0,0.0,0.0],2]
select Users --query '_key:Alice'
[[0,0.0,0.0],[[[1],[["_id","UInt32"],["_key","ShortText"]],[1,"Alice"]]]]

It generates select.actual file that contains actual result. If it is expected result, rename it to select.expected:

% mv select.actual select.expected

Run grntest again:

% grntest select.test
.

100% passed in 0.1736s.

It compares actual result and content of select.expected and reporots compared result. If they are the same contnet, grntest reports success. If they are not the same content, grntest reports failure and show diff of them.

Change --query '_key:Alice' to --query '_key:Bob' in select.test:

table_create Users TABLE_HASH_KEY ShortText

load --table Users
[
{"_key": "Alice"},
{"_key": "Bob"}
]

select Users --query '_key:Bob'

It says the expected result that is read from select.expected and the actual result are not same. And the difference of them is shown in unified diff format. It is helpful to debug the test.

select.reject file is generated on failure. It contains the actual result. If the actual result is the expected result, rename it to select.expected.

% mv select.reject select.expected

Run grntest again:

% grntest select.test
.

The test is succeeded again.

Advanced usage

There are more useful features. They are not needed for normal users but they are very useful for advanced users.

There are advanced features:

  • Comment
  • Continuation line
  • Directives

Comment

Groonga supports comment line by #.

Example:

# This line is comment line.
select Users

Grntest also supports the syntax. You can use # as comment mark.

Continuation line

You can break a long line by escaping new line with \.

Example:

select Users \
  --match_columns name \
  --query Ken

The command is processed as the following command:

select Users  --match_columns name   --query Ken

You can make your test readable with this feature.

Groogna doesn't support this feature.

Directives

Grntest supports directives that control grntest behavior.

Here is directive syntax:

#@NAME [ARGUMENTS...]

Here are available NAME s:

  • disable-logging
  • enable-logging
  • suggest-create-dataset
  • include
  • copy-path
  • long-timeout
  • on-error
  • omit
  • add-important-log-levels
  • remove-important-log-levels
  • sleep
  • collect-query-log

ARGUMENTS... are depends on directive. A directive doesn't require any arguments but a directive requires arguments.

disable-logging

Usage:

#@disable-logging

It disables logging executed command and executed result until enable-logging directive is used. It is useful for executing commands that isn't important for test.

Example:

#@disable-logging
load --table Users
[
{"_key": "User1"},
{"_key": "..."},
{"_key": "User9999999"}
]
#@enable-logging

select Users --query _key:User29

See also: enable-logging

enable-logging

Usage:

#@enable-logging

It enables logging that is disabled by disable-logging directive.

See also: disable-logging

suggest-create-dataset

Usage:

#@suggest-create-dataset DATASET_NAME

It creates dataset DATASET_NAME for suggest feature. It is useful for testing suggest feature.

Example:

#@suggest-create-dataset rurema
load --table event_rurema --each 'suggest_preparer(_id, type, item, sequence, time, pair_rurema)'
[
["sequence", "time", "item", "type"],
["21e80fd5e5bc2126469db1c927b7a48fb3353dd9",1312134098.0,"f",null],
["21e80fd5e5bc2126469db1c927b7a48fb3353dd9",1312134105.0,"er",null],
["21e80fd5e5bc2126469db1c927b7a48fb3353dd9",1312134106.0,"erb",null],
["21e80fd5e5bc2126469db1c927b7a48fb3353dd9",1312134107.0,"erb","submit"]
]

See also: --groonga-suggest-create-dataset option

include

Usage:

#@include SUB_TEST_FILE_PATH

It includes SUB_TEST_FILE_PATH content. It is useful for sharing commands by many tests.

You can use include in included file. It means that an included file is processed in the same way as a test file.

If SUB_TEST_FILE_PATH is relative path, SUB_TEST_FILE_PATH is found from base directory. Base directory can be specified by --base-directory option.

Example:

init.grn:

#@disable-logging
#@include ddl.grn
#@include data.grn
#@enable-logging

ddl.grn:

table_create Users TABLE_HASH_KEY ShortText

data.grn:

load --table Users
[
["_key"],
["Alice"],
["Bob"]
]

user.test:

#@include init.grn
select Users --query _key:Alice

See also: --base-directory option

copy-path

Usage:

#@copy-path SOURCE DESTINATION

It copies a path from SOURCE to DESTINATION. You can use it for both file and directory. It is useful for using fixture data.

You can use #{db_path} in SOURCE and DESTINATION. #{db_path} is expanded to the path of the database.

Example:

#@copy-path fixture/query_expander/tsv/japanese_synonyms.tsv tmp/synonyms.tsv
register "query_expanders/tsv"

long-timeout

Usage:

#@long-timeout TIMEOUT

It specifies a timeout for commands that may take long time. TIMEOUT must be a number or default. If you specify default as TIMEOUT, the default timeout is used. The default timeout is 180 seconds.

Here are the commands that may take long time:

  • column_create
  • register

Example:

# Wait 300 seconds until commands that may take long time output their results
#@long-timeout 300
column_create Lexicon users_name COLUMN_INDEX Users name
# Reset custom timeout for commands that may take long time.
#@long-timeout default

on-error

Usage:

#@on-error ACTION

It specifies a action on error. ACTION must be default or omit. If you specify default as ACTION, the running test is continued. If you specify omit as ACTION, the running test is aborted and the running test is marked as omitted.

Example:

# Omit this test if TokenKyTea tokenizer isn't available.
#@on-error omit
register tokenizers/kytea
# Don't omit this test when any error is occurred in the following commands.
#@on-error default

omit

Usage:

#@omit REASON

Omit the test with REASON.

Example:

# Omit this test until the feature is implemented.
#@omit "This feature is not implemented yet."
new_excelent_command

add-important-log-levels

Usage:

#@add-important-log-levels LEVEL_1 LEVEL_2 ...

Add LEVEL_N to important log level list. grntest outputs log messages when their log level is included in important log level list.

The default important log level list has the following log levels:

  • emergency
  • alert
  • critical
  • error
  • warning
  • notice

If you want to test log messages for info, debug or dump log levels, you need to add the log level to important log level list.

Example:

# Enable logs for debug level
log_level --level debug
# Collect debug level log messages
#@add-important-log-levels debug
log_put --level debug --message "This is a message"
# The following messages is collected by grntest
#|d| This is a message

remove-important-log-levels

Usage:

#@remove-important-log-levels LEVEL_1 LEVEL_2 ...

Remove LEVEL_N from important log level list. grntest outputs log messages when their log level is included in important log level list.

The default important log level list has the following log levels:

  • emergency
  • alert
  • critical
  • error
  • warning
  • notice

You can remove them from important log level list. You can only remove log levels added by add-important-log-levels.

Example:

# Enable logs for debug level
log_level --level debug
# Collect debug level log messages
#@add-important-log-levels debug
log_put --level debug --message "This is a message"
# The following messages is collected by grntest
#|d| This is a message

# Disable collecting debug level log messages
#@remove-important-log-levels debug
log_put --level debug --message "This is a message"
# No message is collected by grntest

sleep

Usage:

#@sleep SECOND

It stops execution while the specified seconds.

Example:

load --table Users
[
{"_key": "User1"}
]
#@sleep 1.5
# Run select after 1.5 sec.
select Users --query _key:User1

collect-query-log

Usage:

#@collect-query-log [true|false]

It collects messages from query log and prints them.

Example:

#@collect-query-log true
select Users --query _key:User1
#@collect-query-log false

Options

Grntest has many options. You don't need to specify many of them because they use suitable default values.

This section describes some important options. You can see all options by grntest --help. You will find many usuful features from it.

--test

Usage:

% grntest --test TEST_NAME ...
% grntest --test /TEST_NAME_REGEXP/ ...
% grntest --test TEST_NAME1 --test TEST_NAME2 ...
% grntest --test /TEST_NAME_REGEXP1/ --test /TEST_NAME_REGEXP2/ ...

--test option specifies tests that should be ran. It is useful when you are interested in only one test.

For example, the following command line runs only vector-geo-point test.

% grntest --test vector-geo-point ...

You can use --test option multiple times to run only multiple interested tests.

For example, the following command line runs only vector-geo-point and hash tests.

% grntest --test vector-geo-point --test hash ...

You can use regular expression to select tests by /.../ syntax.

For example, the following command line runs tests that have geo in its name.

% grntest --test /geo/ ...

You can also use multiple --test options with regular expression.

See also: --exclude-test option

--exclude-test

--test-suite

--exclude-test-suite

--gdb

--keep-database

--n-workers

--n-workers option is very useful. You can run many test scripts at once. Tests are finished quickly. You should specify one or more directories that contain many test scripts. If you have only a test script, --n-workers is not effective.

Here is a sample command line to use --n-workers:

% grntest --n-workers 4 test/function/suite/suggest

--base-directory

--database=PATH

Usage:

% grntest --database /PATH/TO/EXISTING/DATABASE ...

--database option specifies an existing database that is used for test. Normally, grntest uses a new empty database for test.

--database option is very useful for testing against existing database.
