When I test my Angular project on Travis-CI, two exceptions emerged:
$ ng test
The test command requires to be run in an Angular project, but a project definition could not be found.
The command "ng test" exited with 1.
$ ng e2e
The e2e command requires to be run in an Angular project, but a project definition could not be found.
The command "ng e2e" exited with 1.
The error message is pretty confusing. I googled about "Angular project definition", but nothing relevant is found.
I checked out Angular CLI wiki,
but there is no useful information about ng test and ng e2e,
not to mention the definition of "project definition".

UPDATE 1
I just installed the lastest Angular CLI (v7.0.4) on my PC,
$ ng version
Angular CLI: 7.0.4
Node: 8.9.3
OS: win32 ia32
Angular: <error>
... animations, cli, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router
Package                      Version
------------------------------------------------------
@angular-devkit/architect    0.10.4 (cli-only)
@angular-devkit/core         7.0.4 (cli-only)
@angular-devkit/schematics   7.0.4 (cli-only)
@schematics/angular          7.0.4 (cli-only)
@schematics/update           0.10.4 (cli-only)
rxjs                         6.3.3 (cli-only)
typescript                   3.1.3 (cli-only)
and generated a new project testprj with it.
When I execute ng test in directory My Projects/testprj/,
everything goes fine.
Karma v3.0.0 server was started, Chrome browser was launched.
However when I execute ng test in directory My Projects/ng-dementor/,
Angular CLI gives me nothing but "The test command requires to be run in an Angular project, but a project definition could not be found."
UPDATE 2
